Clary POV

My head hurts a lot, I think I have a slight fever too. But we have a mission to investigate my house due to a strange aura around it, and since it's my house I have to be there. I got up, showered and dressed in a t-shirt, jeans, sneakers and wore a midnight cloak. I applied an extremely small amount of makeup to cover the red face. Then I went to our meeting place. Alec, Jace and I walked to my apartment. Jace seems to know something is wrong with me but I keep waving off his concerns. When we entered the door, and was about to start searching, someone came in.

"Who are you?" Jace asked ready to fight.

"Hello, prophecy child. It's been forever. How's your fever?" He asked ignoring Jace. I clutched my head as I felt a stab of pain as I leaned against the wall and soon was on my knees.

"Clary? Are you okay?" Jace came up to me.

"Ethan." I hissed. "Tell me, did your leader, Kronos do this?" I weakly began standing up.

"You are correct Clarrisa Fairchild. Now will you join us?" Ethan replied grinning. I grabbed my snowflake necklace and pulled it off. It turned into a sword, with the guard in the shape of a snowflake. I charged at Ethan attacking. He took out his sword and blocked. Then he got behind me and stabbed me in the shoulder. I turned around to attack him when he got behind my back again and stabbed me in my abdomen.

"Too slow Clarrisa Fairchild." He said as he disappeared. The last thing I saw before I blacked out was Jace and Alec leaving willingly.

Percy POV

I saw Ethan enter a warehouse, so I called Annabeth to tell her to hurry here. When she did, we slowly walked in ready to attack, to find a red hair girl injured on the floor holding a snowflake necklace. We checked if she was still alive and picked her up and took her to Camp Half-Blood. She passed through the borders just fine so she was probably a demigod. We explained everything to Chiron and he told us to keep her in the Infirmary for now until she heals. She wouldn't let go of the necklace and held it as if it costed her, her life. We fed her ambrosia and nectar so she can heal.

Clary POV (in a dream)

"Where am I?" I asked no one in particular.

"In a dream." A man said as he appeared. "My name is Poseidon the Greek God of the Ocean, and you are my son's daughter. You see, once while Zeus was drunk, he made a bet that if I ever had a daughter with a Shadowhunter, then he would bring every god to give that child a gift. I paid a visit to Apollo, who told me that if I had a son, then he would have a daughter who would be even more powerful than if I had a daughter right away. So I listened to his advice and had a son, named Valentine, who I regret having so I took away every power he had that all my children has." He paused for a second

"That's my Dad, right? That's why you claimed me? But no offense, but I still hate him." I said.

Poseidon nodded "And so, when you were born, I held Zeus to his promise, even though you weren't my direct daughter. I took you up to Olympus, and the gods each gave you blessings."

"Zeus gave you power over the winds and lightning; I gave you the power any of my direct children would have of course; Artemis gave you control over most beasts; Nyx gave you strength and wits in night; Apollo gave you a gift with art, Hera gave you the ability to call for her, but will help only once; Aphrodite gave you beauty, as I see you've grown into and will continue to, as well as Charmspeak, which will grow as you use it more often; Demeter gave you the aid of all plants and Karpoi; Hestia gave you sanctuary in your home; Hades gave you the ability to sense death;" This made me remember the feeling I got when Jace died (but got revived). I thought it was Valentine who sent me the warning.

"Dionysus, though he might not remember it now, gave you the ability to make any plant bear fruit, or make poisonous fruit edible; Athena gave you her wisdom and a piece of intelligence; Hephaestus made you a fire-user, since your mother was a child of Hephaestus, he knew you already had a power over machines, but Hephaestus made it stronger; Hebe gave you a long life, where you will never feel the effects of age; Hecate gave you control over magic; Ares gave you superiority in battle, even over his own children, but he didn't like the fact that you were going to be a girl; Nemesis gave you immunity to the urge for revenge; Hypnos made it so that you won't have nightmares, an important thing for Demigods;" My head was spinning as Poseidon went on.

"There were many more, with mostly useless gifts, but some may be helpful one day. In the end, they all believed that anyone so powerful must have a powerful weakness. So, we brought up the Werewolf king, Lyncan, much to Artemis' distaste, who gave you a curse. To this day, we do not know what it is, nor how it will affect you, because he wished it to be a secret." "Wait." I asked "Why did you pick Lyncan? And my step-dad is a werewolf does he have anything to do with Lyncan." Poseidon looked down "No he probably doesn't, because Lyncan is from Greek and Luke is a descendant of the angel. We believed that the most evil would bring a curse most suiting. Now, I must go. You are about to wake up, but remember one thing Lyncan told us that you can control your curse by memories. I came to you because I sensed painful memories, and I want you to know that a single unwise slip of the past could seriously hurt you."

I was glad Poseidon was my grand-father. Then his gaze turned stern "I need to leave you, but remember this dream, daughter. Please. And I consider you as my daughter. Oh and if you're ever rebellious then it's from me." He winked and then, the dream swirled into darkness as I woke up.

I opened my eyes to find myself not at Luke's home or the Institute. I quickly sat up and instantly regretted it as I felt a stabbing pain.

"Easy there." A voice said. I looked up to see a black hair boy with sea green eyes.

"Who are you?" I asked very suspicious. They could be Valentine's helpers for all I know.

"My name is Percy Jackson, son of Poseidon." Percy said.

"My name is Clarrisa Fairchild, I prefer the name Clarrisa Fray or Clary." I said.

"Why?" Percy raised an eyebrow.

"None of your business. I appreciate you helping me but I have to go." I said standing up. I nearly fell if Percy didn't catch me.

"Careful. You should stay in bed." Percy said.

"I hate Infirmaries." I said.

"We should go see Chiron before you leave then." Percy suggested.

"Fine." I sighed and we found this person called Chiron. Except he wasn't a person. He was a centaur. Not that I'm surprised, after all that shadow hunting business, it won't surprise me if dragons exist.

"Chiron. Clarrisa said she wants to leave." Percy said.

"But isn't she a demigod? Won't it be too dangerous." Chiron asked.

"We don't know she is one yet. How about you wait until dinner, so we can see if any gods claim you."

"All this waiting game. Next thing you know you'll tell me to wait for a year to see if they claim me." I grumbled.

"Percy you can show her around." Chiron said ignoring my comment. Percy showed me around, he said I could practically be anyone's child because of my gifts that the gods gave me (not that he knew).

Soon, dinner came. I stood by Chiron really nervous. All eyes were on me when I was claimed by none other than Poseidon. I saw Percy jumping with excitement saying "I have a sister" as if it was a chant. Percy's girlfriend who I believe was called Annabeth punched him in the head. After dinner I walked with Percy to our cabin. I gave a quick call to Luke.

"Luke. Sorry but I needed some time away. Well he did leave me willingly. There wasn't any service so I couldn't call you earlier. Yes. I found some friends and I'm staying with them for the summer. Take care of mom for me-, you WHAT?!" I nearly screamed. "Fine I'll call him."

"Hey sis. What's going on?" Percy asked.

"Nothing to worry about." I smiled as I called Jace since Luke made me.

"Hey Jace. Luke told me to call you. What do you want? I don't care if you're sorry now. It won't change a thing. Now goodbye. I'll be back at the end of summer." I hanged up on him.

For the rest of the summer, Percy, Annabeth, Grover and I had lots of fun. We would go on small quests after apologizing to Grover about leaving him out ten thousand times. I was free from the Shadowhunter world at least for a short while. Also thanks to the quests, I got many clothes as Annabeth insisted that I needed more than just camp clothes. I had a near run in with the shadow hunters a few time and managed to escape them. Percy and Annabeth had practically tied me up and was threatening me to tell them about why we were avoiding those people. So now only Percy, and Annabeth knew about my shadow hunter life. When summer ended, I asked Chiron if I could tell my guardian who I consider my step-dad about the Greek Gods. Chiron gave me permission and that's what I'm doing now in a cab with Annabeth and Percy and the 3 Fates arguing about who gets the eye.

When we finally arrived at Luke's apartment I knocked on the door. The door opened with Luke standing there half-awake and after a moment he hugged me tight.

"Luke-. can't. breath." I struggled to say.

"Clarrisa Fray. I'm so glad you're back. I missed you so much. You look a little different." Luke said scolding me.

"Sorry Luke. I needed some time alone away from the shadow hunters after that incident. So I went to this camp where I me these two, who are my best friends including Simon of course. And I missed you too." I said gesturing to Percy and Annabeth. Luke is right, my hair was longer (because the only way to cut it at Camp was with a knife), and had an icy blue highlight. Dad was right and I had grown more beautiful, credit to Aphrodite's gift.

"Thank you for taking care of Clary for me." Luke said. "Would you like to come in for tea?"

"Sure." Annabeth said. We all sat down while I served tea.

"Luke I have something I need to tell you." I began.

"Are you pregnant?!" Luke asked.

"NO! Oh and Percy that's $20 for me." I said as Percy groaned. "You know about the Greek Gods right? *Luke nodded* Well they're real, and Annabeth, Percy and I are demigods. Half god and half human. But in my case I'm half god and half shadow hunter."

"I don't believe you." Luke said after thinking a little.

"Yes! Another $20 for me." I said as Percy groaned again and started whining about little sisters stealing all your money. "And I have proof if you want it Luke. As much as you deny it, it'll still be real."

"What proof?" Luke asked. I took the cup of tea and made it float spelling out the words 'it's all real -Clary'.

"Did you do that?" Luke asked.

"Yep. Me and Percy are children of Poseidon god of the Ocean so we're half brothers. Annabeth is a daughter of Athena, goddess of wisdom." I said.

"Two brothers in one month. Well I don't have much choice but to believe you." Luke sighed.

"At least this one doesn't have an ego the size of Texas." I chuckled. Then a flash of gold appeared and hugged me.

"Clary I'm so sorry and I missed you so much." It said.

"Jace? You think sorry will help? Did you know how much it hurt when you left me? I couldn't care less if Alec leaves, we never got along well anyways, but it really hurt when you left." I glared as I tried to break away, which didn't work. So I looked at Percy for permission which he gave. So I manipulated the tea and splashed it over us. Of course it didn't get me wet.

"Why you do that? And why are you dry? Wait who did that anyways?" Jace asked shaking himself dry.

"I did Blondie. Now leave me alone." I said. "Let's go you two lovebirds." I dragged Percy and Annabeth out the door and to Percy's home with our bags in their hands. I let go of the two when we were outside Percy's home and knocked on the door. Percy's mom answered it.

"Hello , I'm Percy's friend and half-sister. I was wondering if I could stay over for the year since I have no where else to stay." I asked politely. Percy and Annabeth were staring at me with their jaws wide open.

"Of course you can." Mrs. Jackson said ignoring Percy's and Annabeth's shocked expressions and waved me in.

"What? I can be polite when I want to." I said when I saw their expressions.

"Except you never had before." Percy grumbled as we stepped inside. We hanged out in Percy's room chatting about killing monsters and gossiping about Percy behind his back (which Percy whined about his girlfriend and sister ganging up on him), when suddenly a portal opened and out stepped Isabelle Lightwood, Alec Lightwood, Magnus Bane, and Jace Wayland.

Dun Dun Dun. Now whats going to happen?
