1941. Greece. For 12-year-old Petros, World War II feels far away. But when the Germans invade Greece, the war is suddenly impossibly close. Overnight, neighbors become enemies. People begin to keep secrets (Petros's family most of all). And for the first time, Petros has the chance to prove himself to his older brother, Zola. Soon what were once just boys' games become matters of life and death as Petros and Zola each wonder if, like their Resistance fighter cousin, they too can make a difference. Based on the true story of Akila Couloumbis's wartime boyhood, Newbery Honor winner Audrey Couloumbis, writing with her husband Akila, explores what it was like coming of age in Nazi occupied Greece, and tells a story of family, friendship, and unlikely heroes.
