This book is about three kids Jupiter,Pete,and Bob who like to investigate things.This book is very good and exciting and may I ad a little bit scary and funny like when they meet this kid Brit who is dyslexic (sees letters in the wrong order.) and jupe showed him a business card and he thought it said the three nivetsitagors another exciting part was when they realized that they were on a volcano. I give this book five stars. 
I’ve never even heard of this book. Thanks for introducing it to me and to the rest of the class. I’m glad you liked it so much.
I also am impressed by how many categories this one book fits into. Pretty cool.
Suggestion: Re-read your review and look for grammatical errors like capitalization mistakes and run-on sentences. It should not take you too long.
Cool book review how about the 3 paragraphs.
