Query: This book stinks -- literally!

Medieval Muck is a lot of fun. In addition to the smells (they're not ALL bad), there are many bits of historical trivia. For example, you'll learn more than you ever wanted to of the death of Thomas Becket. Kids who like the Goosebumps books will probably love this series. I can't wait to smell my way through more history.
