There are, I believe, a couple dozen titles now in the Discworld series, but this one -- the fourth -- is still one of the best. Death, who SPEAKS IN ALL CAPITALS, and takes his job seriously, decides nevertheless that he's in need of a break. So he takes on an apprentice, a young farm lad named Mortimer -- Mort for short. On his first solo soul-collecting assignment, Mort discovers he can't allow the teenaged Princess Keli to be assassinated by her uncle the Duke, tries to prevent what is supposed to happen -- what *must* happen -- and, of course, messes thing up. Reality tends to heal itself in the long run, though, and there's no way the kid can stop history from getting back on its proper track. But he's certainly going to try. As one might expect in a Pratchett yarn, things get a bit out of hand after that, especially when Death goes AWOL for a time, trying out human experiences and vices, and when Mort begins taking on more and more of his boss's characteristics. After all, as Mort explains to Death's adopted daughter, Ysabell, DEATH IS WHOEVER DOES DEATH'S JOB. The final confrontation between Mort and Death is a marvelous set-piece. Can Mort win? Can Death lose? Is it even fair? THERE IS NO JUSTICE, as Death is fond of remarking. THERE'S ONLY ME.
