Ending the world is harder than it looks… Librarian Anna Fray has spent her life fighting the prophecy that says she'll rise as War, the fourth horsewoman. War clansmen don't find love, don't enjoy life, and usually have lives that are short, brutal, and lonely. But now that all three of her friends have risen, becoming War seems as unavoidable as late fees. After all, the knitting club just burned down her house, and an arrogant pigeon is starting bar fights and claiming to be War's horse. There's no escape…until she discovers a loophole: find another candidate, and maybe she won't have to become War. Loki - yes, that Loki - is used to being hated and mistrusted, and knows he's better off alone. But he's worked for decades on his ultimate plan to save humanity and Anna is key. He might have a soft spot for the town librarian who was once his ward, but he'll do everything he can to convince her she's the best and only candidate for War. Unfortunately, he hadn't accounted for the fact that Anna is all grown up, completely immune to his abilities and far too seductive for his peace of mind. As passion burns between them, the fate of the Four will be decided…along with just what kind of apocalypse awaits humanity.
