Query: better and better...

There are enough comments about the plot here; so, I just want to say the following. So far, this series has kept getting better and better. The first book was a little "cupcake" where Dead and a Doornail and its immediate predecessor, Dead to the World, remind me of vintage Anita Blake. No, Sookie isn't becoming a tough-as-nails killer of supernaturals. Instead, the setting and complexity of the characters is getting better and better. There is more depth to the setting, plots and subplots, and I love it.
