Under Suspicion (Underworld Detection Agency #3)

She's the new head of the Underworld Detection Agency's strangest division. What a nightmare. . .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. . .
