If you like reading fantasy, then you should pick up a copy of The Warded Man, by Peter V. Brett, when it comes out on March 10, 2009. I really think this is the best fantasy novel I've read since George R. R. Martin's A Game of Thrones.
The Warded Man has everything you need to make an excellent fantasy novel. It has strong characterization with interesting characters. It has an interesting plot. There's solid world building. Most of all, it's an original story.
It's the tale of a young man named Arlen, who witnesses the killing of his mother by demons. These demons arise every night and kill any human or animal they can find that isn't protected by magic wards. Arlen vows to find the ancient fighting wards that allowed men to fight the demons millennia ago.
Seriously, I liked this book. The sequel is definitely on my want list when it comes out.
