Bucking the trend for books about wizards who go to school to learn wizarding, this is a book about a wizard who has to figure it out for himself. It's written more as a set of linked short stories than a true novel. In itself, that's not a problem, but the author leaves many loose ends as Jake (the wizard) goes from one adventure to the next. I liked the secondary characters, especially Fluffy the dragon, Jenny and Princess Esmeralda, and the book is a quick and easy read.
The main thing I didn't like about the book was that Jake's magic seems to be able to do anything the plot requires. There are no spells as such; he just imagines what he wants to happen, and it happens. Sometimes he's not sure whether he can do something, but he usually tries it, and it works anyway. Spells never seem to go wrong, or have unexpected side-effects. Because of that, I seldom felt as though Jake or the people he cared about were in any danger, and so the book lacked suspense.
