Jennifer A. Nielsen, award-winning author of A Night Divided and Rescue, artfully weaves together the stories of five kids living through World War I, each of whom holds the key to the others' futures ... if they are lucky - and brave - enough to find each other. World War I stretches its cruel fingers across Europe, where five young people, each from different backgrounds and nations, face the terror of battle, the deprivations of hunger, and all the awful challenges of war.
