The book is a sort of picaresque, following 15-year-old Adrià Guinart, who has left his home in Barcelona to fight in the Spanish Civil War. He's given a job doing kitchen work, but doesn't last long among the militia. He spends the remainder of the book wandering the Spanish countryside from village to village, where he is by turns beaten up and shunned or taken in and cared for by the people he comes across. Death, destruction, and brutality are everywhere, but occasionally there is kindness. Adrià is hungry, injured, and traumatized. His nightmares blend into his reality, and sometimes reality is the nightmare.
I would respectfully disagree with the statement that there's not much war in this book, though I can see what led the publisher to say it. The war is more in the background than in the foreground of the book, but at the same time, it is everywhere. As in The Time of the Doves, War, So Much War tells the experience of war from the perspective of the civilians who are living through it. (I think it's fair to call Adrià a civilian, even if he did try and join up; he is a child.) The war permeates every aspect of their lives, but they still need to find food to eat, tend their land, bury their dead. This is the reality for most people living through war. The stories of war aren't just the ones about soldiers on the front line.
