Book 4 of the Sookie Stackhouse series - of True Blood fame. This book was so fun. Sookie and Bill are broken up and witches have cursed Eric such that he has lost his memory. Hijinks ensue.
Again with the adding more supernatural elements. The final battle scene involved vampires, witches, werewolves and a really bad shape-shifter. It also introduced the scary people that live in the "Hotshot" neighborhood. They were introduced in Season 3 of the True Blood, but this book took their story arc in a slightly different direction.
Also, as Season Three of the TV show further developed Jason's character, this book hints at the direction that story might go. It looks like Alcide is sticking around, which is awesome. Although we know that the "canon" isn't necessarily the TV canon.
I do miss LaFayette.
