This book is so great. It keeps you entertained on rainy days, in car trips, or whenever you're just bored. The book has puzzles inside of puzzles. It's impossible to do it with a pen since you erase so much. I also has humor through out the book. A great collectable if you have already read the spy school series, but you can play the puzzles without reading books too. Over very great and keeps you entertained, in fact you forehead is going to hurt from the amount of times you slap it. Read more

My son loves the spy school books, and this has been really fun and challenging for him. It’s cool to have this in addition to the other books in the series. Read more

This book is an exciting addition to the Spy School series! It’s full of action, humor, and clever twists that keep you hooked from the start. The main character is really fun to follow, and the spy-themed challenges add a nice level of suspense. The pacing is fast, making it a great read for younger audiences, though as an older reader, I found some parts a bit predictable. The dialogue is witty, and the plot keeps you engaged, but I wish there was a bit more character development. If you're a fan of the series or enjoy books with a mix of adventure and mystery, this one won’t disappoint! Read more

My daughter (and I!) are obsessed with this whole series. We read them together every evening and they are just awesome. She is 12, and they are adventurous, funny, clever and even touch on pre-teen topics in a very tactful way (crushes, etc). Read more
