I got a book, Terry Pratchett, Feet of Clay.
hope you've read guards, guards! and men at arms before you read that!
Nope, I just asked for Terry Pratchett... Sorry
Men at Arms is quite possibly the best of the Discworld novels in my opinion. The only one that competes with it from my viewpoint is Small Gods.
But yeah, Trezk, Feet of Clay is like, the 17th book of the Discworld series, and more importantly, the 3rd one in the Guards series. While not essential to understand what's going on, it does help a lot... especially with the recurring gags and all.
Good reading none the less. Go Cheery Littlebottom!
