Cold Days (#14) Dresden Files by Jim Butcher. Cold Days is the 14th in the series of wildly successful fantasy novels from Butcher, and his writing style is better than it's ever been before. I highly recommend this series.
Jim Butcher... Jim freakin' "Longshot" Butcher. Creative, fun, witty, totally sci-fi and totally awesome. I mark his Dresden Files series a one of my favorite sets of "brain candy" books. They're fun, engaging, and they're like Pringles- once you pop, you just can't stop.
