This is, I believe, the first really good, mid-sequence, Discworld novel. Terry has warmed up, it's a novel without Rincewind, and it's not about a generic fantasy world. It's about the theatre, psychology and the nature of truth. Kinda. The characters are excellent, the plot runs wonderfully, and every sentence is a joy to read. At this point, he's really on a roll, following up with Pyramids and Guards! Guards!. Happy, happy, joy, joy!
