Read a good book lately?

My son just finished reading The Red Badge of Courage. He mentions it several times a day, even tried to get me to read it. I grumbled that it was indeed good but I was familiar with it.

Regroup here: this is what I've wanted for several years, but he's not interested in my choices. So I'm halfway through, it's a quick read after all.

Does anybody have a suggestion for his next book? He (currently) says he likes war stories.
