Men at Arms, by Terry Pratchett

I can't help it, I love everything Pratchett writes. Sometimes, you really need a little humor in your life, and I know I can always count on Pratchett's books to make me laugh out loud. He's just so delectably British, and so irreverently original. His books are actually basic mysteries, but nearly unrecognizable as such due to being wrapped in a thick candy coating of fantasy. Only someone as smart as Pratchett can make surprisingly intelligent humor so effortlessly fun. His books provide a very welcome respite from the more "serious" literature I sometimes read, and I always pick them up with great expectation and glee.
