Levi might be hot, strong, and have a cool set of wings, but it's not enough to make up for keeping Allie in the dark. Allie's tired of being left with more questions than answers. She's tired of loving a guy who refuses to level with her. Most of all, she's tired of her life spinning out of control. Desperate to save Jess no matter the personal cost, Allie has to face the possibility that the only one she can trust is herself.
