A/N: Hello my fellow House of Anubis and Percy Jackson fans! I decided to be original and write a different crossover.

FULL summary: Nina Martin is a daughter of Athena. She lives in Camp Half-Blood and is pretty good with a curves knife. When news from a wind nymph name Trudy comes about a monster and 8 half-bloods, Chiron assigns her on a quest to rescue the half-bloods. If only it was that easy. Nina makes enemies, friends and a possible boyfriend. Takes place in season 1 and after TLO.

Rated: T, adult language, and suggested 'adult themes' (thought they're all funny)

Pairings: Percy/Annabeth. Nina/Fabian. Amber/Alfie. Grover/Juniper. Clarisse/Chris. Mara/Mick. Mara/Jerome. Amber/Mick and many more

"Are you almost done packing, Nina?" asked Annabeth, walking into our cabin; the Athena cabin.

I looked up from my suitcase. "Yeah," I replied back, folding a purple T-shirt and neatly packing it away. "I'm done with my clothes. All I have to do is pack the demigod stuff." I said.

Annabeth nodded. You see, Annabeth is my half-sister. Our mom is the goddess, Athena. You know the goddess of wisdom and crafts. Anyway, I'm heading to Liverpool, England for a school year. Usually I stay with my Gran for the school year or, rarely, at Camp Half-Blood-the only safe place for demigods to live- but not this year. They're eight half-bloods in a boarding school in England. We had a wind nymph named Trudy keeping an eye on them till we could figure something out here.

"Many powerful auras," Trudy had said in a resent Iris Message. "We only have one monster here. But a powerful one, I'm afraid."

Annabeth, Percy Jackson, the Stolls, Katie Gardener, Will Solace, Drew Tanaka, Clarisse La Rue and I all sat around the ping pong table in silence as our centaur trainer, Chiron spoke to Trudy

Chiron sighed. "We'll send somebody. I promise."

Trudy smiled warmly. She'd taken a liking to those kids since she'd been watching them for more than 7 years old, disguising herself as their housemother. "When?"

"Soon," Chiron promised, scratching his beard. "We'll send one demigod at a time. Everyone is still on edge since the Second Titian War." Everyone in the room nodded. "We'll send Nina first." That surprised me. I'm only second in command of the Athena cabin. "She's a good fighter and good with people."

"I can't go alone." I blurted out.

Chiron gave me a reassuring smile. "Don't worry dear. We'll send someone when you say your ready to leave with the demigods. Deal?"

I nodded.

Trudy clasped her hands and was about to continue when a door opened.

"Alfie! Jerome!" yelled a girl. "Go away Alfie!"

"Got to go, does are the dearies." Trudy said in a hush voice. "We'll speak later." Then swiped her hand through the IM.

"Nina!" yelled Annabeth.

"Huh?" I asked dumbly.

Annabeth rolled her eyes. "What backpack do you want to pack your demigod stuff in?"

I went to my bookshelf and grabbed a gray, owl print backpack. "This one," I said, throwing the bag to her. "You going to miss me?" I asked.

Annabeth shrugged playfully. "Don't know. You're just my sister."

I punched her in the shoulder and we finished packing. I had plenty of ambrosia and nectar packed away in a Ziploc baggy and a thermos.

"I better get dressed," I said, gesturing to my pajamas. "I don't think the security guards will like an orange T-shirt and owl print PJ bottoms."

Annabeth nodded with a chuckle. "I'm going to go talk to Percy." She said.

"Oooh…" I smiled wickedly. "Someone is going to go see their little boyfriend."

She punched me in the arm. "Shut up," She headed to the door. "I'll see you before you leave to say goodbyes."

I smiled. "Okay." Of course I had to add. "Use protection with Percy."

Let's just say Annabeth's face has never been so red.

A/N: Hoped you liked it! Please review, I'd mean a lot to me. :) And let me know what you think of this idea...?
