Ace and Bub, The Flying Beaver Brothers, are back for another graphic novel adventure. This time they are pitted against a corporation, Fish Sticks Environmental Manufacturing. When the brothers literally fall into the path of the company, they uncover information about this allegedly eco-friendly business that reveals...it's evil. Luckily, the brothers are clever and athletic, skills that will help them in their quest to defeat the bad guys.

While the first book in the series was not overtly environmental, this book takes more of an activist approach. Author Maxwell Eaton's choice to make green the main color of this book ties in nicely with the theme. The illustrations remain as cute as in the original and I hope that they make plush Beaver Brothers toys some day.

The reading level of The Flying Beaver Brothers and the Fishy Business seemed to be much higher than the first in the series. I read both books over the course of two days with a low-level ESOL student. He struggled a lot with the more complex vocabulary and heavier emphasis on text in this book. Hopefully readers who have gotten hooked on the series will not be frustrated by a more challenging reading experience.
