What happened to Professor Perez? Young sleuths will be eager to unravel the mystery in this interactive story packed with logic puzzles. When the Codebreakers Club’s beloved professor goes missing, it’s time to get to the bottom of this puzzling problem. Chris, Kaira, and Ren soon discover some very intriguing notes written in the professor’s distinctive handwriting. The catch? The Codebreakers must solve puzzles he’s left behind to get the next clue! Key features include: More than 150 logic puzzles, including crosswords, logic grids, rebuses, word searches, cypher codes, and more for kids 9–12 Engaging topics such as history, science, geography, and pop culture Fun, fast-paced mystery with hints and tips from characters while honing critical-thinking skills and logical-reasoning aptitude Review: Interesting and entertaining for adults too - Great "interactive" story with various kinds of puzzles to keep you interested and entertained! I know this is a children's book technically, but as a 29 year old adult with a lot of downtime at a register - I bought this book for myself and I really enjoyed it. I have your standard adult crossword/word search/sodoku puzzle books and they're fine for a bit, but I tend to get bored after doing 3 in a row. However, this book with its incorporated story line was something that i didnt get bored of. Wish there were more in a series or something. Highly recommend for all ages, as in adults can do them too, no shame! Review: Great for a Travel Activity - Purchased as a travel activity for our 9yr old on a flight. Great for some light mystery reading and brain puzzles. Love this for kids that dont always love to read because it has short (1-2 page) reading excerpts of a story they follpw to help solve a mystery with math, patterns, riddles, etc.

My daughter thought it was a lot of fun
I got this for my 11 year old to do along with her school work. She absolutely loved it! Some of the puzzles were more of a challenge for her than others, but she still enjoyed them all.

Good book
It’s a great book but needs kids to have some general knowledge as well. Helps them learn but need some help.
