DISCLAIMER: I don't own PJO, Rick does.

Prologue:

Annabeth had simply been walking toward the apartment that she and Percy shared when a human looking creature had jumped out at her.

She didn't know what it was or what to do.

So when it clasped its hand over her mouth and began drinking her blood she did the only rational thing she could think of doing.

Reaching for her knife, she bit its hand in attempt to get the creature off of her.

Big mistake.

It began to push its hand tighter against her mouth, letting blood seeped into her mouth and down her throat. She choked against the tightened hand, dropping the knife she had in her hand in shock. The vampire was still drinking her blood.

Slowly, she began to feel woozy, losing her consciousness. She could feel her heart beating overtime to try and keep the small amount of blood left in her body still flowing. The vampire stopped sucking on her neck, looked her in the eye, and twisted her neck, snapping it.

Annabeth woke up the next morning in an alleyway. She didn't remember much about how she got where she was, but she did remember what happened. The vampire, the blood, her snapped neck.

She should be dead.

But somehow she wasn't. She didn't know how or why she was still alive.

And she was not about to put it up for debate.

Quickly she rushed to Percy's apartment, not too far from where she was, and where she was supposed to be the night before. He was probably going out of his mind looking for her. She opened the door, which was unlocked and walked in to see two police officers sitting down at her living room table, Percy's face stained with tears.

He looked up at the noise of the opened door, making eye contact with the girl he thought was missing and smiled. Percy rushed up to her, hugging her tightly.

"Where have you been?" he asked, not letting go quite yet. Annabeth debated telling him what really happened, but thought better of it. She didn't know what Percy would make of it.

"I got caught up at my camp," she said, covering it up easily, "we had some… action," she said, and Percy understood. He knew she meant barrier action. Sometimes monsters follow newfound demigods to the border of camp, and they don't leave right away. More than once they have had to send Annabeth and the Ares kids to problem solve. That was when she noticed the policemen staring at her. "There's no problem now officers. Thank you," she said, and they simply got up and left, leaving Percy and Annabeth alone.

Annabeth ran her fingers through Percy's hair, sliding them down the length of his face. She smiled at him, inching closer to his lips. Her palms slid down to Percy's neck, and all of a sudden his pulse felt like it was surging through her body. She ripped her hands off of his neck and whipped away from him, feeling the skin on her face tighten up. Her jaw began to ache and she let out a shriek of pain. Percy rushed over to her gripping her.

"Annabeth are you okay?" he asked, a pained look on his face. As she felt his touch, the pounding got worse and she had the desire to do something no human would have the desire to do.

She had the itching desire to bite down on Percy and drain all the blood from his body.

She shoved him away.

"No, Percy, don't!" she yelled, rushing to the door and opening it, flinging herself out of the apartment and into the hallway. She didn't know what she was going to do, but she couldn't hurt Percy, she had to get away. She ran down the hall.

At the end of the hall, she could hear Percy shoving on his shoes and following her.
