Starred Review. Something Evil (that's with a capital E) is stalking Gil's All Night Diner in Martinez's terrific debut, a comic horror-fantasy novel. Heading the delightfully eccentric cast are buddies Earl (aka the Earl of Vampires) and Duke (aka the Duke of Werewolves), who are looking for a place to eat as they drive through Rockwood, a small desert community besieged by cosmically weird stuff. Soon after stopping at Gil's Diner, the pair help Loretta, the formidable owner-operator, fend off a zombie attack. Determined to do the right thing, the two supernatural misfits take on further challenges, such as trying to prevent Tammy (aka Mistress Lilith, Queen of the Night) and her loyal but dumb boyfriend, Chad, from ending the world. The fast-paced plot is full of memorable incidents (e.g., a ghost and a vampire fall in love; a Magic 8-Ball becomes a message vehicle for trapped spirits) and such wonderful observations as "this whole undead stuff sounds good on paper, but it ain't all it's cracked up to be." Fans of Douglas Adams and Joe R. Lansdale, who supplies a blurb, will happily sink their teeth into this combo platter of raunchy laughs and ectoplasmic ecstasy.
