Jason goes undercover in a juvenile detention facility to make friends with Andrew Cho whose father is part of a diabolical plan to get people hooked on drugs by putting them into a popular breakfast cereal. Once Jason has passed all of his tests with Cho's family, it is decided that he can be an asset to them, so Jason begins his undercover work to find out who is behind the drugs and how they can be stopped. Jason's efforts work almost too well, and it isn't long before he is on the run.

Revenge is a very problematic book. There are major issues with pacing and content. For a middle grade book, there are a large number of adult themes and ideas. Action and adventure dominate the story, but the inclusion of so much death is disturbing. Jason once again does amazing things, especially for someone his age, but as in the first book in the series, it would be so much better if Jason was aged up a few years to make the impossible seem a little more within the realm of believability. Overall, the story in Revenge is built on an absurd plot with underdeveloped and underage characters. ( )
