Percy Jackson An unexpected alliance c1

Based after the first Titan war Annabeth has moved to NYC to go to school with Percy, her dad rented her an apartment. She has a roommate a great boyfriend and everything seems to be going great... she should know better that a demigods life is never simple. Monsters come back with a vengeance only for her to get help from an unexpected friend. Will she and Percy overcome these new dangers? What exactly are the gods trying to do? Will include Heroes of Olympus

AN: So this is my first Percy Jackson ff, I hope you enjoy. I do not own any Percy Jackson characters.

Annabeth walked into her apartment with a sigh. Today was a long day not as in fighting monsters or fighting for survival but a more mundane thing school. Annabeth loves learning new things she is the daughter of Athena after all even with dyslexia she still thrives on learning new things. She had completed two tests today one for history the other English and in between had to put up with Niki Campbell the high school popular girl who is hell bent on taking Annabeth down. If it weren't for Alexa she was sure by now she would have beat Niki to a pulp. Alexa was her roommate as well as her classmate. Whenever she wasn't in a class with Percy she had a class with Alexa these two people seem to keep her anger in check. Which Annabeth found strange seeming she was usually the cool headed one in hot situations but everything about Niki sent all her senses out the window.

"Hey I brought dinner." Annabeth stated looking over at Alexa who was sitting cross legged on the floor like she was meditating. Annabeth looked over her friend with brown hair and tanned complexion she reminded her of a goddess in her own way. She wore jeans and a singlet her hair hanging loosely down her back, she always looked perfect without even trying. Much like the daughters of Aphrodite but Annabeth knew her friend was not a demigod she was a normal girl with an intelligence about her that made Annabeth get along great with her. The only thing that Alexa did that Annabeth did not like was that she did not like Percy. She was never outright rude or mean but she also never went out of her way to get to know him either.

"You know you do not have to bring me dinner right?" She asked opening her eyes and facing her, her brown eyes bore into her soul making Annabeth shuffle on her feet moving over to the table.

"Sally said she hardly sees you eat so makes it her mission to watch out for you. Well us considering she knows we will be studying."

"Ms Jackson?" Alexa asked smiling, she had met Percy's mum several times and seemed to like her. She still remembers the first time they met. Sally came over to their apartment looking for Annabeth but was greeted by Alexa when she saw the state of the apartment (no food in the cupboards or fridge) Sally made sure it was her mission to make sure they ate.

"Yes, she made extra and said if you would not join us you should still get something to eat."

"Hey Annabeth about today..." Alexa stopped as she grabbed the food to look up and meet her eyes.

"Niki deserved it." Annabeth shrugged seeming that Niki had come up to them with her group of friends when Annabeth was at her locker shoving Annabeth hard against the locker getting right up in her face telling her she should leave. Alexa had by this point 'tripped' over her own feet knocking Niki to the floor getting up and standing on her hand. She had no idea how she got out of trouble seeming she was sent to the principal's office then two minutes later she left and that was the end of it.

"Oh she deserved a lot more but still my behavior was out of line. I did not mean to make things hard on you."

"If you are referring to what her friends had said to me, trust me that was nothing. You had my back...did I thank you?"

"I don't recall?" She asked smirking before both girls ended up laughing.

"What are you doing tonight?" Annabeth asked

"Nothing, I have finished my assignments... maybe watch a movie?"

"Right well I need to study."

"When you are not with Percy you study you know that right?"

"Yes."

"You also know that today was the last day of our tests. We can now relax?"

"I still like to study."

"And that Chase is why I do not get you. Nope tonight we are going to watch a movie. Yes I like this idea it will be a girls night." Alexa stated smiling heating her food up in the microwave before moving over to the tv. "I will even be nice and let you pick the movie?" She added

"Fine...I could use a night to relax." Annabeth agreed moving over to the couch before sitting down Alex gave her the remote before getting her food and claiming her spot next to her on the couch. They ended up watching tomb raider as the movie finished Annabeth looked over to see Alexa asleep on the couch. Annabeth smiled this girl could fall asleep anywhere on par with Nico. Annabeth moved over and grabbed her book before heading to her room to at least get a head start on her reading for their next subjects.

"Chase let's move it, I will not be late because of you." A voice called into Annabeth's room she groaned, she had a terrible sleep filled with a horrible nightmare.

'Annabeth was running through camp shouting at the others to hold steady she saw campers fall on either side as she ran to Percy who was fighting something large and dark. Thalia was there with the other hunters shooting arrow after arrow but to no avail. A menacing laugh filled her ears followed by a deep voice.

"You cannot stop me champion, I will destroy you and your friends." Annabeth kept running but found herself falling into darkness' before being promptly woken by her roommates voice. Annabeth looked at the clock and jumped into action getting ready in a heartbeat she moved out of her room to see Alexa at the table with a coffee cup in her hand she saw gratefully that there was a second cup next to her which Annabeth claimed.

"Damn Chase you look terrible, I thought I told you that you were supposed to relax, how late were you studying for?"

"You're right sorry."

"Whatever you do, do not fall asleep in class because even I will not be able to save you from that embarrassment."

"We should go if we don't want to be late."

"Waiting on you Chase." Alexa replied grabbing her bag, heading for the door. Annabeth did the same and followed her out. It was a crisp sunny morning that you could still see your morning breath in the air as Annabeth followed Alexa to her car.

"We are picking up Percy yes?" Annabeth asked

"Yes, seeming his mother sees the need to feed me it is only polite that I offer her son a lift." Alexa replied they picked up Percy and headed for school.

"I don't want to ruin our relationship or anything but what do you plan to do about class today." Percy asked Alexa who clenched the steering wheel tighter.

"Not much I can do, I do not have a family so I cannot do this assignment." She replied "You and Annabeth should understand what with only one parent...see touchy subject. Sorry did not mean to bring up bad memories."

"My fault I shouldn't have brought it up, just know that you have us." Percy stated.

They entered home room together to see most of the others already seated as the bell rang. The teacher came in to take attendance before getting them started on their assignments. One by one a student went up and talked for three minutes about their family. Percy went up and talked about his mum and stepdad, Annabeth went up and talked about her father, step brothers and step mother. Both of them were asked about their other biological parent Niki being the one to bring up Annabeth's mother. Alexa was called up, she actually was hoping that they would run out of time but unfortunately luck was not on her side. Annabeth saw Alexa take a deep breath before she began,

"My family...that is something I don't usually talk about. My parents were killed when I was young and my family as you call it is rather unconventional. When I think about family two people come to mind...sure there have been others that I do consider family but without these two I would not be here. One who is like a mother figure the other like a sister."

"Are they blood related?" Someone called out

"Sort of."

"How can you be sort of blood related?"

"Blood transfusion...I was hurt and without her I would be dead."

"How did your parents die?" Another kid called out everyone could see that Alexa
was getting really uncomfortable Annabeth was about to step in but thankfully the teacher did before she could move, not before Alexa whispered

"Monsters." She looked at everyone who was looking at her before promptly leaving the room. Percy looked at Annabeth it seemed they were the only two to hear Alexa's confession. Percy gave her a specific look that Annabeth could read.

'She didn't mean actual monsters right?'

Annabeth got up and followed Alexa ignoring the calls from the teacher she found Alexa in the bathroom clinging to the sink. She was trying to get her breathing under control but was failing. Annabeth places her hand on her shoulder and had she not been a trained warrior Annabeth would have been punched.

"Hey it's just me." She said getting more concerned when Alexa's eyes widened.

"Sorry so sorry I did not mean..."

"Hey it's alright."

"GodswhydidItellthem that...I should have lied...why didn't I lie?" Alexa stated

"Come on."

"Where are we going?" She asked as Annabeth pulled her out of the bathroom.

"We are leaving."

"School? You Annabeth Chase wanting to ditch?" Alexa asked but was still extremely agitated, she still managed to use mock surprise.

"Where to?" A voice stated making Alexa jump but Annabeth smile.

"What are you doing here?"

"I brought your bags." He said holding up the point of subject.

"Let's go seaweed Bain." Annabeth stated heading for the exit, Alexa clearly surprised they were not stopped by any teachers. Percy ended up driving much to Alexa's dismay but seeming her hands were shaking she only complained the once. Annabeth sat in the back with her as Percy drove them to the park. They sat on the grass in their disclosed area that they had discovered earlier on in the year. Sitting in silence for a while before Annabeth and Percy talked softly with each other. They then took Alexa back to Percy's place where they were greeted by Sally, surprising Alexa that they were not in trouble. She sent Percy and Annabeth away, talking with Alexa alone.

Annabeth was pacing inside Percy's room looking at the door several times Percy had to stop her from walking out.

"What are you thinking about Wisegirl?"

"This is the first time I heard her talk about her past."

"You are still stuck on her confession at the end. She might not have meant actual monsters it could be a name for evil men." Percy pointed out.

"I do not know."

"If she was a demigod we will know...right you already knew."

"Yes she is not a demigod...she could be like your mum though and Rachel."

That night they had dinner there and Sally settled everything at the school. Annabeth and Alexa returned to their apartment heading straight for bed.

Annabeth tossed and turned in her sleep tortured by nightmares all the same she was at camp and there was a fight many of her friends were hurt and injured and when she went to Percy she ended up falling always to that menacing laugh.

"Annabeth...Annabeth." Annabeth bolted up right her hand going for the attack only for it to be stopped. Annabeth looked up into Alexa's brown eyes that bore deep into her soul, no warmth or kindness neither hate or anger but simple concern.
"You were screaming." She explained

"Sorry, nightmare."

"It is alright...here." She said handing her a glass of water no not water but hot chocolate. "Helps scare away nightmares." She stated Annabeth sat up looking her friend over.

"I did not wake you, you were already up?"

"Yes. I was reading when I heard your scream."

"You had nightmares too?"

"I will tell you mine if you tell me yours." She stated but could see Annabeth was not wanting to share. "Try to get some sleep." She stated before turning around and leaving her room.

Alexa had been spending a lot of time with Annabeth which Annabeth really enjoyed as they did really normal things from watching movies to taking walks around the city to talking about school. It was finally getting close to summer vacation where the feel of normalcy was growing close to an end, Annabeth knew that she might never see Alexa again when she left for camp and was concerned at what will happen to her considering her dad had made it possible for her to stay with Annabeth instead of being at a group home. She even talked to Sally about this, seeming Alexa was close with her now. It was a week before summer holidays would begin and Annabeth was dreading it. Especially because most nights now were filled with nightmares and Alexa had woken her out of them most nights. Her friend was starting to show the effects of lack of sleep but still never complained, always making sure she was safe. It was a Saturday morning and Alexa had spent half the night trying to consult an upset Annabeth so she grumbled as loud excessive knocking made her leave her bed.

Alexa went to open the door at a constant sound of knocking, it was Saturday who would be up this early on a Saturday.

"What do you want?" Alexa asked seeing Percy standing at the door.

"Annabeth in?" Percy asked

"She is still asleep...it is early Jackson." She replied and Percy moved inside as Annabeth came out of her room, looking like the walking dead. Percy went over to her and pulled her in for a hug as Alexa went over and made her a cup coffee handing it over to Annabeth before moving over to the couch and reading a book.

"Are you okay?"

"I am fine, it is just..."

"Nightmares?" Percy asked

"Yeah, what about you?"

"Nightmares? No...hey I need to tell you something." He whispered looking over at Alexa but she was already engrossed in her book.

"What?"

"I think I saw your mum."

"What?"

"Yeah when I was walking up here I thought I mean it looked like her..."

"She...I didn't see her..."

"It might not have been her..." Percy stated

"Yeah... in my dream I think she was giving me a message."

"What message?"

"After my nightmare and Alexa woke me up I finally got back to sleep and there was an owl in it...basically the jist of it was trouble is coming."

"Hey guys..." Percy jumped to see Alexa standing behind them. "Do you guys want to go out today?"

"Sure." Annabeth stated looking at Percy he could read in her eyes she wanted one day to be normal. So the three of them moved around New York heading to the fair where they spent the day before heading to the movies in the evening. When the movie was finished they walked through the streets heading back for the car when Percy froze and looked behind them.

"Annabeth!" He stated trying not to sound too panicked

"What? Oh by the gods." She cursed lightly

"Everything okay?" Alexa asked making Percy and Annabeth share a look with each other.

"Nothing...why don't you head back to the apartment I want to hang with Percy for a little while longer." Annabeth stated looking at Alexa as Percy kept an eye on the monster moving towards them. Annabeth noticed Alexa's eyes widen as she stood their frozen.

"What is that?" Alexa asked

"What?"

"That! You have to see it right? Please tell me you see it?" She asked Annabeth

"We can't fight it." Percy said. "Not here. We need to draw it away from the city."

"I will drive." Alexa said Annabeth could see she was still scared but her eyes looked determined.

"If we are going to do something we should do it now." Percy said he pulled out his pen making it into his sword.

"You have a sword?"

"You can see this?" Percy asked

"I am not blind of course I can see it."

"Run for the car now!" Annabeth stated pushing Alexa along and Percy brought up the rear. They made it to the car and climbed in the monster giving chase but Alexa was great behind the wheel taking off and diverting through the traffic.

"Where too?" She asked weaving in and out of cars with precision.

"Left, we need to get out of the city." Annabeth called out as Percy kept looking back through the window.

"Camp?" He asked

"Yeah, camp."

"What about her?" He asked just as Alexa got them out of the city. Before she promptly stopped turning to face Annabeth.

"Why are you stopping?" Percy asked

"I am not going anywhere until you start talking. What was that thing? Why do you have a sword? Where are we going?"

"I promise to explain everything but we need you to drive." Annabeth stated as Percy called out that he could see the monster.

"You better Chase." Alexa grumbled as she reeves the car and once again took off.

"Damn were you a nascar driver in your former life?" Percy asked as she swerved in time so the monster missed the car.

"Where to? There is nothing out here but farm lands." She stated

"See that ridge? Get us there and I will answer all your questions." That was when she pulled off a complicated maneuver that had the car skidding along the road missing the monster that landed in front of them. She cursed as her tires gave out and was doing everything in her power not to lose control of the car any more than what she had so far.

"You guys alright?" She asked slightly dazed happy that the car had not flipped but her neck was stiff and her belt felt like it had dug into her skin.

"Get out!" Annabeth practically shouted as she got out she grabbed her hand and ran for the ridge.

"Annabeth." Percy called out as they made it to the top and through the barrier only to find that Alexa was still next to them. She had made it through the barrier without getting permission.

"What the?" She asked looking dazed and amazed then confused. She stumbled and Annabeth grabbed a hold of her to steady her. "My head..."

"It is a lot to process."

"The monster is gone." Percy said looking back the monster that chased them is nowhere to be seen.

"We need to take her to Chiron." Annabeth stated

"Who?" Alexa asked "what is that? That was not there a second ago? Is that a camp?" She asked as Annabeth guided her towards the big house not surprised at all to be met by Chiron, he did not seem to look at all impressed with Alexa's presence.

"Annabeth, Percy I hope you have a good explanation..."

"You're a horse?"

"Centaur." He replied

"That's a myth?"

"I can assure you I am not a myth." He looked irritated

"No I suppose not...I think I am losing it..."

"That could be a possibility." Chiron states making Alexa frown and Annabeth gasp Chiron has never spoken this way towards anyone.

"That's rude." Alexa commented glaring at the centaur Percy had to admit she was taking it really well and it was one mean glare.

"I will talk with your friend in private; Percy, Annabeth why don't you return to your cabins I will bring her over once I have finished talking to her." Chiron stated guiding Alexa inside she looked at Annabeth for reassurance but felt Chiron guide her in. Annabeth looked like she wanted to follow so Percy guided her away and back towards the cabins. Not many were here considering there was still a week to go before summer officially started only those that stayed year round were found here. Percy went off to send an iris message to his mother as Annabeth paced in front of her cabin looking back towards the big house. It felt like forever until Chiron came over with Alexa who was looking around the camp Annabeth could tell that her friend seemed annoyed but was trying to hide it. Chiron then left her with Annabeth who gave her a tour of the camp before running into Percy again.

"So Lexa what do you think of our camp?" Percy asked, again Annabeth noticed the annoyed look flash in her eyes.

"Interesting...that Chiron guy said I need to stay here..."

"For now, you won't be here forever." Percy stated although as he said it he did not sound so sure. He had managed to grab Chiron and talk with him, apparently the mist had no effect on Alexa so they could not convince her none of this happened. He had said she would stay here until he can think of something else.

1 week had passed and in that time other campers had slowly been turning up, now most of them were back all curious about Alexa who by this point had been keeping to herself. Annabeth had been trying to keep her company and each day she would ask when she got to go home. Annabeth has spoken to Chiron and Mr D who had offered to make Alexa go insane so no one would believe her Annabeth had shut him down rather quickly. Alexa had been staying in the big house and was currently walking next to the lake, Annabeth had welcomed some of her half siblings before going to find her.

"Hey."

"Hey." Alexa replied she was sitting on the beach looking out over the water.

"You know you can join in on some of the activities?"

"Against half gods no I am good...have they agreed on when I can leave?" She asked hugging her legs.

"I'm sorry." Annabeth stated

"You keep apologizing... the only thing I want is to return to...never mind."

"Annabeth!" A voice called out she turned to see her brother Malcom was calling her over.

"Come with me..."

"What are you doing?"

"My cabin has the arena."

"No I am good, I saw you sparring with Percy I think I will wait here." She replied as Annabeth looked at her friend and sighed she had withdrawn so much over the week her sarcastic nature was gone and she had become so quiet she was getting worried.

Annabeth moves over to the arena getting her siblings under way she ended up sparring with Malcom who grunted under the force of her attacks. She only stopped when they heard a horn.

"What is that?" Malcom asked not recognizing the sound

"Hunters." Annabeth smiled she was eager to see Thalia again. Campers moved towards the clearing in time to see hunters walking down the hill led by Thalia. Annabeth started to pick up her pace smiling brightly at her old friend only for it to turn into a frown when she saw Alexa running towards them with a bow in hand, where did she get the bow from?

"Wait." Annabeth shouted out seeming several of the hunters had grabbed an arrow.

"κάτω." Alexa shouted and Annabeth was in amazement seeing the hunters drop to the ground and roll to the right as Alexa fired her arrow, several of the hunters followed her trajectory and fired their own arrows that was when all hell broke loose and a giant monster appeared.
