The best!!!!!!!!!!!!

Great book, especially if you love puzzles.

This is an action-packed book with clues and puzzles along the way to the end. I recommended this book to my dad, and anyone else looking for a great read.

I loved this book so much! I was always on my toes and the suspense at the end was crazy! It made me think of friendship because even though the boys didn't really want to hang out with a girl, they still became friends. And if the main character had not had his friends, he might not have been able to figure out the mystery! So if you like mysteries, puzzles, and amazing plot twists, this is the book for you!
