This book was tons of fun. Our MC is Max, or rather "Just Max". He sort of just gets by in everything, but then one night he gets a card from the Chaos Club.

This event is a disaster of sorts, but sets Max on a path of becoming "Not Max". He, and the other "Water Tower 5" victims decide to embark on a prank war. During the months that follow, Max grows and changes, like any well written YA protagonist should, and I throughly enjoyed his journey.
I loved the pranks, the banter, and the friendships that grew from this common bond. I loved all the references to great heist films, and all the accompanying "rules". I have read some people calling this "Ocean's Eleven meets The Breakfast Club" and comparing it to a hybrid of The Goonies and The Breakfast Club, and I say, "YES!".
You will cheer when the Five succeed, and feel a little bummed when they fail, but man, you will laugh, smile, and fist pump many times along the way.
