Next in my attempt (after finishing that SFBC omnibus, which screwed it all up) to read the Discworld novels in order. Coming up are Wyrd Sisters, Pyramids, and Guards! Guards!, in that order.

Pratchett, Terry. Mort. 1987. New York: HarperTorch, 2001.
Summary: The Discworld Series #4. Mort becomes apprenticed to Death and, by not liberating the soul of the Princess Keli when he's supposed to, causes a reality paradox on the Disc. In the end, Mort almost but not quite ends up becoming the real Death, Albert, great wizard cum Death's servant, manages to right things, and Death pardons Mort for the error of his ways and dismisses his service. Mort then marries Death's daughter Ysabell.
Comments: A charming, inoffensive retelling of a "revenge of the nerd" story...but, as usual, the best parts about it are 1) the imaginative tenor of the Discworld and its flavorful fantasy satire, 2) Death, and 3) the librarian. In that order. This is actually the first novel I've read to have NOT involved Death as a semi-menacing figure pursuing Rincewind, who just won't agree to sit still and die, and, in fact, I was kind of surprised by how fundamentally naive Pratchett made Death. Watching him try out human life was quite amusing--especially when he ends up a short-order cook for a greasy spoon. All in all, it came together quite nicely from a structural perspective and never tries to impress the reader with more than anyone can reasonably handle on a single page as the earlier Pratchett novels did.
Notes: mass market paperback, 11th printing
Rating: 6/10 - Fluff with just enough inventiveness to keep a handful of brain cells firing, at least.
