I read this book fully in 8th grade and thought it was pretty good. Some of the more infantile humor such as the way Rose de Nose is in the first time we see him I could have done without, but it's a very good story with a very engaging plot about how a lot of people would probably react if they were forced into a war that they didn't know they were fighting, that it was all a game. Hollywood Tactics
also goes straight out the window, as Mazer repeatedly points out to Ender. It's a very realistic portrayal of what a kid would go through if forced into a war, to be the perfect soldier, and the book is really good for it.
