What a great narrator! It's easy to identify with this kid-- trying to manage a stressful situation, trying to connect with people, dealing with being different-- even though if you met him in person you might feel uncomfortable around him. The other kids in the book are all individuals with different traits and motivations, and I felt sympathy for all of them as they try to solve adult problems with only the resources available to children.

In addition, the mystery is a good one. The clues are laid out fairly (no sneaky last-minute guesses) and the conclusion is logical without being too obvious. Good for fifth-grade through eighth-grade, plus for mystery lovers in general.

I enjoyed the main character of this book, especially when she is trying to solve problems on her own. I liked her strength and determination as well. And the mystery is solid-- no gaping holes in the plot. A good one.
