This is a fun book of math, logic, and philosophical puzzles. The joy for me came from Smullyan's ability to channel Lewis Carroll. He used the characters, humor, and story lines from Adventures in Wonderland and Through the Looking Glass to great effect.

This is not, however, a math, logic, nor philosophy book. The answers are given in the back, along with a brief explanation of how the answer was reached. It doesn't explain the math/logic etc. I would have liked to have had more of an explanation of how to set up the problem-solving. Because I'm that kind of a nerd who doesn't understand higher math.
