Heaven and Hell are at war.

Heaven is losing.

There can be no right choices.

Homicide detective Alexandra Jarvis's life has been torn apart by the struggle between Heaven and Hell, and humanity has begun a relentless spiral toward self-destruction. Now Michael, the Archangel she holds responsible for Earth's plight, has returned?and he's demanding her help to track a missing god.

Michael's only chance to defeat Hell lies in returning Heaven's long-lost daughter to her throne before it's too late. But first he'll have to convince Alex to help him?and keep her out of Hell's clutches long enough for her to do so.

With the survival of both their worlds at stake, Alex and Michael must put aside their animosity and find a way to work together in the face of increasingly impossible decisions ... and unimaginable sacrifices.
