Child of Artemis

Avalon is a demigod who isn't supposed to exist. Only she and another demigod named Ivan know about her parentage. She is different, even for a half-blood. Her powers are only possessed by herself and her godly parent. Her mother had forsaken the company of men a long time ago, and Avalon was not born naturally.

She was born by magic, when a goddess had been forced to bring her into the world. Now she has to make a place for herself in a world where she has no right to live as she finds Camp Half-Blood and gets her quest.
