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—and that's why it's so much more fun to spill.
