Mr. Benedict's Book of Perplexing Puzzles, Elusive Enigmas, and Curious Conundrums

The Mysterious Benedict Society: Mr. Benedict's Book of Perplexing Puzzles, Elusive Enigmas, and Curious Conundrums - Trenton Lee Stewart, Diana Sudyka

I really enjoyed this companion puzzle book. The puzzles range from pretty easy to quite difficult. My favorite part is that the answer key isn't straightforward. It gives you clues that lead you to the correct answer if you're stuck.

 

You can enjoy this book without reading The Mysterious Benedict Society first, but I think fans of the series will get more out of it than someone just looking for a book of puzzles.
