Eric

Eric by Terry Pratchett is about a young boy who attempts to summon a demon to grant him wishes, but instead of a demon, Rincewind, an inept wizard shows up inside the magic circle. Much to Rincewind's surprise he finds that even though he is not a demon, because he was summoned as one, he has the power to grant wishes. Hilarity then ensues because as the old saying goes, be careful what you wish for. This book was a short but fun read and I'd definitely recommend it to fans of the Discworld series or just if you enjoy British humor.
