I think I may be reading the best book of the year right now: Cold Days (The Dresden Files #14). I'm half way through, trying not to devour the book so as not to forget the details.
The worst was definitly: 101 Tips for Traveling with a Vampire. This was supposed to be a funny, paranormal short story. Instead, it was, as I stated in my review: "forced, sophomoric, cliched and unfunny". In other words -crap!
