So, a bit of context (pun not intended) for the people who are not familiar with the series (if you've heard of True Blood, it's a loose adaptation of the books): the basic premise is that, since synthetic blood has been invented, vampires are able to get out of the closet (and they did); we follow the story of Sookie Stackhouse, who's a waitress in a small town in Louisiana, and has a tendency to have a fair amount of drama, murders and power struggles around her. The whole series is easy-read, obviously you'll want to avoid it if you're allergic to vampire stories, but apart from that it's entertaining and funny.

It's the 12th book in the series, but all books are of reasonable size (contrary to some other fantasy series I won't name here :P), so by now the setup is pretty well-defined, we know all the characters, and it's essentially comfy.
In the whole series, I felt this one was kind of not as good as the others - still enjoyable, but missing a certain je ne sais quoi - maybe some funny one-liners (although I did laugh quite loudly at the sentence "Claude was standing absolutely still, doing a great imitation of Switzerland", but then I was in a tram in Zürich, so...), maybe a bit of action - the mood was kind of bittersweet all along, which is not necessarily a bad thing, but I hope the next one will be a bit more upbeat :)
