I think this book is pretty cool. It is cool because they go into the sewers and get all dirty. I love getting dirty when I play soccer. The book has no pictures but it does put a picture in your head. It has really good descriptions. I liked Jack because it seems like he is the one who does all the action. Andrew Clements has other books written by him, like Frindle. His writing style is really easy to understand. I hope you go to the library to check out this book and read it.
I recommend this book for 4th and 5th grade students because it has no pictures and hard vocabulary. This book mostly fits people who like getting dirty because you're about to go to the sewers and get lost in there.
