When half-human Cal Leandros wakes up on a beach littered with the slaughtered remains if a variety of hideous creatures, he's not that concerned. In fact, he can't remember anything - including who he is. And that's just the way his deadly enemies like it.

After saving the world from his fiendish father's side of the family, Cal Leandros and his stalwart half-brother Niko have settled down with new digs and a new gig - bodyguard and detective work. And in New York City, where preternatural beings stalk the streets just like normal folk, business is good. Their latest case has them going undercover for the Kin - the werewolf Mafia. A low-level Kin boss thinks a rival is setting him up for a fall, and wants proof.

Halfhuman Cal Leandros and his brother, Niko, aren't exactly prospering with their preternatural detective agency. Who could have guessed that business could dry up in New York City, where vampires, trolls, and other creepy crawlies are all over the place? But now there's a new arrival in the Big Apple. A malevolent evil with ancient powers is picking off humans like sheep, deadset on making history with an orgy of blood and murder.

Half-human/half-monster Cal Leandros knows that family is a pain. But now that pain belongs to his half-brother, Niko. Niko's shady father is in town, and he needs a big favor. Even worse is the reunion being held by the devious Puck race - including the Leandros' friend, Robin - featuring a lottery that no Puck wants to win. As Cal tries to keep both Niko and Robin from paying the ultimate price for their kin, a horrific reminder from Cal's own past arrives to remind him that blood is thicker than water.

Once, while half-human Cal Leandros and his brother Niko were working on a case, an ancient gypsy queen gave them a good old-fashioned backstabbing. Now, just as their P.I. business hits a slow patch, the old crone shows up with a job. She wants them to find a stolen coffin that contains a blight that makes the Black Death seem like a fond memory. But the thief has already left town, so the Leandros brothers are going on the road. And if they're very, very lucky, there might even be a return trip.
