I'm reading the Southern Vampire Mysteries (aka the Sookie Stackhouse's books). I'm totally addicted! Just finished the 4th book, and can't believe I didn't knew it until True Blood started to be aired. And if I was already totally Team Eric, you can imagine right now after reading it... He's so 'oh-my-god-so-fucking-awesome'
If you didn't read it yet, go for it. It's so much better than show!
