Dead as a doornail - Charlaine Harris

Sookie Stackhouse is a cocktail waitress in a little bar in a small town deep in Louisiana. She's funny and pretty and well-mannered, but she doesn't have that many close friends - mind you, that's not so surprising when you consider how few people can appreciate her abilities as a mind-reader. It's not a quality that has the guys beating down her door - well, unless they're vampires or werewolves or the like . . . but they're not just supernatural freaks, some of them are friends, even family . . .

And much as Sookie might want a quiet life, when she's around, things just seem to happen . . . like her brother, who appears to be changing into a were-panther. He's not that bothered, but someone doesn't like it - someone's trying to wipe him out, as well as the rest of the shape-changing population, and that mean's Sookie's got just a month, before the next full moon, to find out who wants her brother dead, and stop the fiend.
