This book was a great book and so entertaining and adventures. some parts are tedious and hard to read some times i had to make myself read it but overall a good and hart warming book. A good beach read

This is the 50th time that I read this book and I can never get tiered of it. Plus, I love this journal thing that are what you read. I wish there was part two of this book!

This book was amazing! When I got it, I read it almost 10 times in one day! Now I take it school, and read it whenever I can! Great book for 5th and 6th graders!

Operation Frog Effect is such a great book! If you like books that have action in them like kids sneaking away for a night and getting into a bit of a scrape and/or books that have a HUGE theme of friendship than you will LOVE this book! I TOTALLY recommend this book to you!

Some kids sneak out and their amazing teacher, Mrs. Graham, gets blamed for it. The class works together to try and get their teacher back. I would recommend this book to people who like frogs and a good mystery.
