All of Bella's life, she has struggled to fit in with the witches in her coven, and a week before her seventeenth birthday when she receives her familiar and learns the truth about herself. Bella is now on the run from an all-powerful demon known as the Keeper of Souls, and while on the run, she learns more of her past from a half demon named Aiden, who would do anything to protect her. Bella and Aiden must get to heaven before it's too late, and Bella unwillingly helps create something that could destroy the world.
