After nearly becoming a sacrifice, Elizabeth vows never to be the victim again. She needs power to protect herself and the ones she loves from the dark forces that pine for her abilities--but this power, dark and consuming in its nature, always comes at a price. Soon, Elizabeth finds herself a slave to the energy that courses through her body. Out of control and angry, she must fight for control or be consumed by the darkness she welcomed in.
