The books are called the Sookie Stackhouse series. They are also known as the Southern Vampire Series by some. There are a total of nine books out currently I will list them in order.
Dead Until Dark - Story arc of Season one
Living Dead in Dallas - Story arc of Season two
Club Dead - Some of this book is making it's way into Season two
Dead to the World
Dead as a Doornail
Definately Dead
All Together Dead
From Dead to Worse
Dead and Gone
I am currently reading the series for the first time. I am really really loving it. I am on the third book now, and I can see why people love Eric so much. He is much different in the books. The books are just as good as the show, if not better.
The books are called the Southern Vampire Mysteries, and in order are:
Dead Until Dark,
Living Dead in Dallas,
Club Dead,
Dead to the World,
Dead as a Doornail,
Definitely Dead,
All Together Dead,
Dead to Worse,
Dead and Gone
Hope that helps!!
