Coy, an Angel/Fallen hybrid, and her gang find themselves on Terminus, where demons lurk in the shadows, and the most terrifying Fallen rules. Despite the danger, leaving isn't an option. Terminus has the means to heal her adoptive father, and she'll do anything to save his life ... and Killian will do anything to protect her. Even use the Flaming Sword of Uriel to shatter the gate to Heaven and lead the Fallen into a battle they'll win.

An act that will destroy everything.

Torn between destiny and love, Coy and Killian must unravel the truth behind the prophecy before fate forces them to make a choice. Either join the darkness or fight against Lucifer's most vicious demons. The apocalypse rests their hands, and the hardest question lies in their hearts. At the end, will they stand with or against each other?
