Michele read this book and liked it, so she recommended it to me. I like it, too. It's funny--at times it's very funny--and fast-moving enough that I didn't feel guilty for reading a diversion rather than something more serious.
One note, though: The cover boasts a comment from Publishers Weekly that reads, "[A] fast, fun, heroic fantasy satire." But this is not a satire--it's a parody. It pokes fun at the conventions of the fantasy form, but it doesn't do so in order to comment on our culture or society.
This is a more mechanical twist of the form than Terry Pratchett generally produces (because Pratchett is king), but it's an amusing read with more depth than I would have supposed prior to reading it. Definitely worth the time.
