This young adult book about a kid at war touches on some interesting topics, while telling a very quick story. Nothing is given a lot of emphasis though, so it could just be an enjoyable read. The issue given the most attention is that the main character is too young to deal with being at war, while his girlfriend is struggling with a biology class. He mentions that he'll be a vet unable to drink legally. He and his buddies spend their free time playing war games, Halo and with silly string. The other take away is how fast they wanted him to get back out in the field, it's mentioned a few times and it's clear to the reader he was not ready.
Not given enough attention is the personal reason this kid is at war. He is doing it to have money for his little sister to go to college. It could have been a completely different book if they had focused more on the lack of serious investigation into the kid's death.
With all these issues just mentioned I don't think kids should read the book on their own, they need an adult to talk to about it.
