Terry Pratchett. Eric. Gollancz, 2000 (originally published 1990). 155 pages.
A cute, short book. It starts off very strong – with Rincewind summoned, mistaken for a demon, and forced to grant the summoner three wishes – but doesn’t really go anywhere interesting. It’s a nice little diversion from the usual end-of-the-world formula of Discworld books, though.
