Master of Space and Time

Well, that was... ok... I guess. Zany hijinks are never as fun as you think they're going to be. The successors to this book are better. If you still want to read about an "anything is possible" world, I recommend The Closet of Discarded Dreams by Rudy Ch Garcia, which I know is a little obscure, but well worth your time. If you want the math and a little bit of the kooky characters, but without fritter and pork chop trees, I recommend Superposition by Daviid Walton.
