My sister read this book aloud to me on a road trip from Seattle to California. It is a work of multilayered artistry to be appreciated from the spiritual to the fantastic. It's also fun and unlike most of Pratchett's books you actually care about most of the characters. Reads well out loud as well. Like many readers here, I see it as the author's pinnacle, the book that he will be remembered for. Here's to immortality, Mr. Pratchett!
Positive
