I will declare my bias here and now – I adore Terry Pratchett, and have done for years. I’m afraid you will find little of objective critique here, just unabashed admiration. If you haven’t yet met him and the world of characters he has created, I highly recommend them to you. In my mind, they are the perfect read for a young clergy-woman’s precious leisure hours.
Pratchett’s most famous books concern the Discworld (so called because it is truly a disc, moving through space on the back of four elephants, standing in turn on the back of a giant turtle.) It is a world peopled by wizards, dwarves, trolls, witches, werewolves and vampires.
