Here's something different: a vampire novel that's light, funny, and not at all hackneyed. Between scenes of punks bowling frozen turkeys on the graveyard shift in a supermarket, or snapping turtles loose in a loft and gnawing on designer shoes, this novel has comic charm to spare. But it also packs an appealingly downbeat message about the consumer culture: Becoming a vampire has given the twentysomething heroine "a crampless case of rattlesnake PMS"--a grumpy mood in which she realizes that she can dress to the nines as a "Donner Party Barbie" and still end up disillusioned and unhappy, just another slacker doing her own laundry and watching sucky TV 'til the sun rises.
