read Children at War by P. W. Singer. I grabbed that book in a hope to collect some material for my father's novel (16th century, a cossak adopts a pre-teen boy who has survived the massacre by Tatars, and then together they chase after the treasures stolen not by the Southern invaders, but by the locals supporting the Polish rulers) and for my own work too - I often work with refugees. Even seeing the photo on a cover, I still thought the photo was used to attract attention, and the book would be mostly about the post-traumatic syndrome in those children who witnessed the violence and about "the sons of the regiment" - the orphans adopted by the groups of adult soldiers. The book turned out to be about the real children-soldiers, the whole squads of minors under 17 and the peacekeepers facing children as enemies. However, I decided to finish the book, I've found lots of facts, both historical and contemporary, for my father, and I think now I know more on what's going on in the regions where "my" refugees come from.
