I'd advise reading "One Word Answer" before Defintely Dead if you're reading the Sookie Stackhouse books as otherwise you feel you've missed a book out. The Anita Blake story is set before Obsidian Butterfly but it doesn't really advance the story much, if you're a fan of Jean Claude it's worth a read though. I liked to Queen Betsy story though I haven't read any of that series yet. I don't think it's much of a spoiler story as it is centered around a vet from another town. "Blood Lust" was OK, nothing great and I didn't read "Galahad" as it is part of a series I have no interest in reading.
