He's a demon bound to the devil. She's a holy weapon promised to an angel. And in a world where Heaven and Hell have both abandoned Earth, love may be the most dangerous rebellion of all.Everly has spent her life sheltered in a sanctified bunker, raised on duty and dogma, trained in ancient runes, and promised to an archangel she's never met. Her path is set-until her bunker is destroyed, her sister vanishes, and Everly is left bleeding in the ruins of a faith that failed her.Enter Walton: a gruff, cigarette-smoking bounty hunter with a demon's mark and a body count to match. He doesn't save people. But Everly isn't part of the job-she is the job. Bringing her to Hell could win him his humanity back. But every moment with her cracks his resolve.As their journey across a decimated world draws them closer-to each other and to the truth-Everly will question everything she's ever believed, and Walton will be forced to choose: damnation, redemption... or a girl who was never meant to be his.If you like the darkest before the light, morally gray men who flirt with bullets instead of compliments, and heroines who pray with bloody hands, you'll devour Ascension.Fans of Supernatural, Fallout, and The Book of Eli-step into a gritty post-apocalyptic saga where faith is fragile, love is forbidden, and the line between holy and hellish is about to burn.
