Dead Until Dark by Charlaine Harris
Okay, so poor Jen and Sean had to watch the ENTIRE season of True Blood over New Year's with me, because after only an ep or two, I was hooked, and they'd already seen it, but I forced them.
And THEN, I got a copy of Dead Until Dark from Jen, the first book in the series. Yay!
Sookie Stackhouse is a telepathic waitress in Louisiana, who falls in love with a vampire named Bill - vampires, by the way, are legal citizens with all rights and responsibilities like everyone else. But not everyone feels that way, so when colleagues start getting killed around Sookie, she starts to get scared...
This novel really follows the first season of True Blood pretty closely (glaring omissions: Tara doesn't exist at all, and Lafayette's fabulousity is SORELY lacking), so of course, I'm eager to get my hands on book two!
Recommended - whether or not you watch the HBO series!
