Meet the D'Artigo Sisters: Half-human, half-Faerie, they're savvy—and sexy—operatives for the Otherworld Intelligence Agency. But their mixed-blood heritage short-circuits their talents at all the wrong times. Delilah shapeshifts into a tabby cat whenever she's stressed. Menolly is a vampire who's still trying to get the hang of being undead. And Camille? She's a wicked-good witch. Except her magic is as unpredictable as the weather, which her enemies are about to find out the hard way...

At the Wayfarer Inn, a portal to Otherworld and the local hangout for humans and beasties alike, their fellow operative, Jocko, has been murdered. Every clue points to Shadow Wing, the soul-munching, badass leader of the Subterranean Realms. He's made it clear that he aims to raze humankind to the ground, turning both Earth and Otherworld into his private playground.

Their assignment: Keep Shadow Wing and his minions from creeping into Earth via the Wayfarer. The demons figure they're in like Flynn. After all, with only the bumbling sisters standing in the way, how can they miss? But the demons have a secret coming: Faulty wiring or not, nobody kicks ass like the D'Artigo girls!
