The last time he followed his heart, Shax ended up in Hell. This time, it just might be his only salvation.

Once Lucifer’s most feared assassin, Shax is stuck on Earth and tormented by the need to find the one who got away. Outrunning supposed friends and definite foes, he takes refuge in Kansas City. It isn’t long before he comes face-to-face with his quarry, the angel Kheone. The smart choice would be to kill her, but for reasons he does not want to examine, he rescues her instead. Now embroiled in the events that closed the Gates to Heaven and Hell, Shax must decide between love and saving his own skin.

Loyal and lethal, Kheone pursues the demons roaming the Earth with single-minded ferocity, fulfilling her purpose to protect humankind. When her friend dies under circumstances eerily similar to the explosion that cast her out of Heaven, she makes a deal with Shax to track down the killer. Struggling to trust her new partner, Kheone fights her growing bond with the demon as they discover the pieces to a puzzle that just might reopen the ways back to Heaven and Hell. Working with a demon has Kheone questioning the very nature of good and evil, testing her loyalty to the Archangel Michael and all the angels trapped on Earth.
