Cal and Niko Leandros return to take back the mean streets of New York from some distinctly unhuman predators

What comes after you've stopped the end of the world?

Cal and his half-brother Niko's lives are settling back to normal after stopping their bloodthirsty relatives from bringing about the apocalypse. They've found a new apartment and even gainful employment by starting an investigative agency in partnership with a glamorous Upper East Side vampire. Of course, their clientele tends to be a little . . . unusual, but their money spends just the same.

Their latest job is undercover work for the Kin - New York's werewolf mafia - to sniff out proof of a set-up by a rival. The location is Moonshine, a gambling club for the otherworldly, and Cal figures it will be an easy in-and-out sort of job. But as Niko likes to point out, nothing is more dangerous than overconfidence and when a brawl gets out of hand, it looks like he's right. Are Cal and Niko being set up themselves? And by people whose bite is so much worse than their bark . . .
