This is the third of this series I've read. I read #1 and #4 well before seeing True Blood. Now that I'm all caught up on the TV show, I thought I'd see how they compare. My first impression, when I first started watching the show, is that it was much more serious in tone than the books. However, I feel that the show has gotten a bit sillier as it's gone on, and now they're much more evenly matched.
Reading this, there was a weird mix of spoilers, things that happened differently in the show, and things that already happened - the show isn't following the books religiously. However, I do feel that it's captured the spirit if the writing.
These aren't Great Books - but I did very much enjoy reading this. It's fun, light paranormal romance.
