Evil Spy School

Evil Spy School by Stuart Gibbs

The protaganist gets kicked out of spy school due to an "issue" with a mock battle. Back in regular middle school, he gets chased by bullies who somehow stop chasing him. The "evil spy" leader has saved him and wants him to join them. He agrees (after realizing that his friends might have intentionally framed him to get him to infiltrate the bad guys.) The bad guys have their spy school (including a girl that barely missed the olympic gymnastics cut.) They have a base disguised as a gated community with missile silos in septic tanks. The good guys barely win.

The pacing works fairly well, though seems a little too long. There are plenty of interesting elements that seem almost plausible, but are clearly played for laughs.
