A.N. Okay, first things first: Hi! This is my first Percy Jackson fanfic, so let me now what you think. Now, this story happens right after they come down from Mount Olympus. Instead of going back to camp Percy and Annabeth go to Percy mom's house. Now, I'm not sure how old Nico really is, but in my story he is going to be 15; a year younger than Percy and Annabeth. So anyway on with the story! Let me know what you think!

PPOV:

"Percy? Percy?" My mom called from across the table.

"Wh-What?" I said, finally snapping out of my little day dream, most of which was about a certain daughter of Athena, who happened to be sitting right next to me.

"I said, 'Are you going back to camp tomorrow? I heard Chiron is going to keep the summer campers for an extra two weeks, if you want to go you could..." She said.

I looked over at Annabeth, "I'm going to go for the two weeks, after that I'm not really sure what I'll be doing..." Annabeth said. Her father, stepmother and half-brothers lived across the country from camp half-blood, and me so it made it a bit difficult.

"Honey, if you would like you could come live with us for the school year, after all, we are moving into the new house and there are two extra-bedrooms, so if you would like, we could make one of those yours.." My mother said.

"Oh, I would love to. Thank you so much Mrs. Bolfis." Annabeth said, shocked, but obviously pleased by the offer.

"Annabeth, why don't you go call your dad and check with him." Annabeth nodded and stood up from her place at the table, walking into the kitchen where the phone was.

This was going to be awesome! My mom and my stepdad, Paul Bolfis, had decided to move into a house. Sure it isn't really in New York City, but it is close enough that I could get to Olympus and Camp in less than half an hour by car. And now Annabeth was going to be coming to live with us! We had started to move stuff into the house so I had seen it a couple of times. It was really nice; it was the type of house you would see in a cute little town, complete with a huge green lawn and a white picket fence. The house had six bathrooms plus a half-bath and five bedrooms... wait five bedrooms. One for Paul and my mom and one for me... that left three not two...

"Mom, there are going to be three extra bedrooms, counting Annabeth's, not two." I said, she must have counted wrong or something.

She glanced at the door that led to the kitchen, after a moment she said, "Honey, you have a little sister."

"Wait, what?" I asked, completely confused.

"When you were four, Poseidon had come to visit. He couldn't stay long and you were at pre-school, he couldn't wait for you to come back... and well... nine months later, you had a sister." She said quietly.

"Then where has she been? And why don't I remember this?" I asked, my voice rising.

"Zeus was not happy, especially since Poseidon 'went back to the same mortal', so Zeus erased your memory of that nine months, this way it wouldn't raise any questions. He was hoping you would not learn about the gods, not learn to fight, and end up getting ki-killed by a monster. So that is why I had to hide you when you turned ten, you were getting too close to the age the prophecy claimed you would become. And she has been with your father all this time."

So first off, I had a sister. Now my mother is telling me she has been with my father this entire time.

"I wasn't allowed to know about the gods, but she got to live with one! And why? Why did she need to go live with him?"

"At a very young age we found out that she was a risk to the secrecy of the gods. I remember we were in the hospital and all of a sudden, the water in the cup on my bedside table, it just started twirling, like a mini-huricane. She was doing that. Poseidon was there. He insisted on being there, after all, he was there for your birth, he had to be there for her birth. Zeus never learned of her until after she was born, after she was hidden. I told him she had died, that I had mis-carried, but he didn't believe me. He searched the world, from Olympus, for her, but he can't search in your father's realm without Poseidon's permission, so he never found her."

"When were you planning on telling me this?" I asked, completely dumb-founded.

The more she spoke of it the more I was remembering it. It seemed like a dream though since I had been young. I remembered her stomach growing and I remember she woke up in the middle of the night screaming. I ran to her bed side and cried, no child like seeing there mother cry. Then a man, who I realize now must have been Poseidon, appeared beside me. I almost screamed out, but he placed a hand on my mother's stomach and she stopped screaming. He then picked her up and held her with one arm, then took my hand in his other. He brought us down to the street where a fancy sports car was waiting. He placed my mother in the passenger seat and put me in a carseat that was in the back. We got to the hospital and in the matter of hours, the baby was born. I never got to see her though since I had fallen asleep. Then we were home. I never wondered about the baby until now...

"I...I..." I couldn't form words. I stood up and walked to the door.

"I can stay!" Annabeth said coming out of the kitchen. "What did I miss?" She asked seeing my mother and I.

"I can't believe you." I said. With that, I walked out the door.

I didn't really have a destination, but I kept walking, and surprise surprise! I ended up at the piers over looking the ocean. I didn't think twice, I just climbed up onto the railing and jumped. I fell a bit, but as soon as I felt the water close around me, I knew I was safe, I knew I was home.

I took a breath and called out "Rainbow! Rainbow! I need a lift." I waited a moment, breathing normally since I finally got a hung of this whole breathing underwater thing, and then I saw a line of bubbles zigzagging towards me and in a matter of seconds, Rainbow the hipocampi (A.N. I'm pretty sure that is what he is. It's the one that likes Tyson...) was floating in front of me.

"Hey Rainbow! Do you mind giving me a lift to Poseidon?" I asked the creature.

He turned around and helped me climb onto his back, and then we were off to see Poseidon.

APOV:

"I can stay!" I said coming out of the kitchen. "What did I miss?" Percy was standing with his hand on the doorknob, halfway out the door and his mother was sitting in her seat, looking down, almost as if she were ashamed.

"I can't believe you." He said and walked out the door, slamming it behind him.

"Um... Mrs. Bolfis? What happened? If he doesn't want me to stay here I can..."

"Oh Annabeth. No no no! He isn't upset with you staying, he is upset with me."

"If you don't mind me asking, what happened?"

"Percy has a little sister. She is four years younger than him and she has been living with Poseidon for the past twelve years. I hardly met her, I don't even know her name."

A lone tear flowed down her cheek. I walked over to her and gave her a hug. I hated to see her cry, she was like my second mom, well maybe third since Thalia had taken care of me when we were on the road, but you get the point.

"Annabeth, you are a good girl and I hope you and Percy can stay friends for a long, long time."

"Mrs. Bolfis? Can I tell you something?" I asked. Annabeth, don't do this! Don't do this!

"Of course, sweetie." She said, looking at me.

Annabeth! Anna- Oh forget it. "I'm not sure if I want to be friends with Percy that much longer..."

"Wait, what? But you two see, to get along so..."

"No, no! I mean I'm not sure if I want to be FRIENDS with Percy much longer." I cut her off, emphasizing the word friends.

"What- Oh..." She caught on and the largest smile I had ever seen crossed her face.

SPOV: Sally

"No, no! I mean I'm not sure if I want to be FRIENDS with Percy much longer." Annabeth said.

"What- Oh..." Oh my gods! Annabeth loves Percy! And Percy loves Annabeth! Yes!

FLASHBACK:

"Mom? Do you think I should go with the Dare's on vacation?" Percy asked as he helped me set the table.

"Percy, if you want to..." I started, but he cut me off.

"I'm not sure. I mean, Rachel's great but what if I'm needed by camp? What if Annabeth needs me?" He asked the last question under his breath.

"Percy? What did you just ask?"

"What if the Camp needs-" He tried to avoid it.

"No the second one."

"Oh that." His face went tomato red.

"What did you say?"

"Nothing."

"Percy."

"Fine. I asked 'What if Annabeth needs me?' Happy now?"

"Yes! Oh my god! Does she like you! Are you two dating! Oh you should!"

"Mom! Mom! Stop!"
