His Atonement by A. K. Graves

A broken woman with dark secrets and a plan that could prove to be her undoing.

A heartless demon on an ill-fated path that could give him everything he’s ever wanted and more, or just as easily, take it all away.
After she’s given devastating news and suffers a heartbreaking loss, Frankie Masters decides to pack her bags and form a plan, one that includes relocating to Ashland, Oregon. Little does she know, this will open the door for things she never allowed herself to have or desire—like falling in love and hoping for a happily ever after before it’s too late.
As a demon nearly two thousand years old, Zan has accumulated more sins than he can ever atone for and he’s been perfectly fine with that until now. Now Zan has to choose between saving his soul or countless others and the last thing he needs is the added complication of finding his mate.
Kindred spirits full of hidden truths and ulterior motives, Zan and Frankie try to ignore the undeniable spark between them, a spark so potent it could easily burn their carefully constructed plans to the ground. When the battle proves to be useless and their efforts in vain, will their bond be enough for them to risk everything in the name of love or will that love destroy them both in the end?
