"Being a human immune to magic helped Sophie Lawson get promoted. It's also made her a major, very reluctant player in a game that stretches beyond even the Underworld. Having handsome buttoned-down Englishman Will as her new guardian is one tempting blessing, especially since sexy fallen angel Alex is mysteriously MIA lately. But as a frightening number of demons start disappearing around the city, Sophie suspects that an Armageddon-level prophecy is about to become everyone's nightmare. And her investigation is testing her bravery-- and Will's unexpected vulnerability-- in ways neither could predict. Now Sophie and Will are fast running out of time as an unstoppable evil prepares to lay waste to demons and humans alike."--p. [4] of cover.
