The Forgotten Daughter

Aliana was basically raised at Camp Half-Blood. She has few memories of her life at home, but those she has retained are not pleasant.
It's been 7 years, she's 14, and her godly parent, her mother, still hasn't claimed her. Refusing to give into her grief, bitterness, and anger, she throws herself completely into her training. She grows to be one of the fiercest warriors at Half-Blood Hill. You would think everyone would be clambering to have her as an ally, but they weren't. The other campers seemed to hate her. They avoided her like the plague. No one wanted to be associated with her. They didn't interact with her unless they had to.
That is, until Percy Jackson arrived.
