Topic: The Dresden Files series by Jim Butcher
I love the Dresden FIles books by Jim Butcher. Part sci-fi part horror, they are very interesting books. Often times funny and with all sorts of monsters. Sure the main character is a wizard, but it still has some very good horror elements to it as well.
On a side note, I think the Sci-fi channel series sucked. They didnt do a good job of adapting the books in my opinion. They tried to make it too cheesy and lost a lot of the content that makes the books work.
