The Story of Gumluck the Wizard by Adam Rex
This is a story about magic, if you like that kind of thing. It is also a story about a ghost with amnesia, an unpopular fairy, an ungrateful little town, and an extremely wise and helpful raven (who happens to be a pretty talented storyteller). But mostly, it is about a friendly little wizard who lives inside a big hill and really, really, really wants to be a hero. His name is Gumluck, and he is a bumbling noodlehead.
In this tall tale about a short wizard, celebrated author Adam Rex proves once and for all that the biggest heroes often come in the smallest nightgowns.
