Kate Lancaster has always done things on her own - never asking for help, keeping herself busy with work, and trying not to let her loneliness chip away at the walls she built. But when she accidentally summons a massive, winged demon into her bedroom - the status quo goes out the window.
Zerachiel spent centuries as a shadow, untethered and alone. He was never meant to be in Coldwater Springs. Bound by ancient magic, he has only one month before Kate must find a way to send him back to the realm he came from. But as days turn into nights filled with a heat neither of them can deny, the question shifts from how he will leave… to if he even wants to.
Yet something lurks in the darkness, watching, waiting. When danger comes for Kate, can she defy fate and claim the life, and the love, she never thought she deserved?
