Laser, Michael. Cheater. 2008.
Karl is really smart. So smart that a group of students ask him to join their cheating group. The kids all come from different groups in school and no one would ever suspect they are working together. They use high tech cheating methods, like using cell phones and electronic pencils that send radio waves. Karl knows it's wrong and tries to get out, but he's in too far at that point. The maniacal Vice Principal starts going after cheaters with a vengeance, vowing to expel everyone he catches cheating. This makes things even riskier, but Karl can't seem to get out of it.
The only aspect of the book I had a problem with was that it was unrealistic. I know kids cheat, and they do it a lot. However, I don't think many are using methods like this. If they were smart enough to organize like this and get it to work, they probably don't have to cheat in the first place. Furthermore, the VP expelling people for cheating was also a stretch. A policy like that would never fly. At the very least, the parents would need to get a lawyer and there would be an expulsion hearing, but that didn't seem to happen here. These sorts of things made the book impossible to enjoy thoroughly.
