Although I kind of don't like the cover, ti doesn't matter! It is one of the most brilliant things I've ever read and I laughed all the time.

I love the part where Magnus got himself drunk and went to the desert to start a new life as a cactus. Me and my friend talked about it so much that we started calling him simply Mactus. Otherwise who wouldn't want to see a drunk warlock an a flying carpet trying to write something in the sky. After I finished reading it there was just one slight disappointment - I didn't get to how why he was banned from Peru, but it didn't really matter because I had had a lot of fun reading it.
