When I first read the title, I was worried that this book was about bombs and guns. However, this is certainly not the case. In fact, the closest Mary Roach gets to bombs is a history of the stink bomb. Instead, this is all about the practicalities of humans at war-sleeping, hearing, intestinal distress and proper clothing. The best recommendation I can give is that she made me care about a subject that I never cared about (or even thought about) before.
