When Alec, the only other day-walker she's ever met, walks into her high school, Dani feels as though the rope was cut beneath her feet, and she'll quickly plummet to her death. Alec claims he wants to protect her from the highest order of their kind, but Dani is not so sure and questions his intentions, trying to understand his sudden presence in her human life. Against all logic Dani finds herself inexplicably drawn into his alluring gaze, but she knows he can't be trusted and struggles to keep her secrets safe. Dani leads a double life that was never meant to intertwine. The real question is, can she trust herself to stay strong as her two worlds collide, spinning her life out of control, and the lives of the people she cares for most, completely out of her hands.
