Why You Should Read This:
This is a good look at the boys after the war, and how they as soldiers have to adjust to having civilian lives. Well, semi-civilian lives. They try at least. Too bad for them the fighting doesn’t really want to leave them behind. The OC’s are well thought out without taking over the whole plot, the plot itself is well written and interesting. And the plot twist near the end? Didn’t see that coming.
