Poland, July 1944. Sixteen-year-old Maria is making her way home after years of forced labor in Nazi Germany, only to find her village destroyed and her parents killed in a war between the Polish Resistance and Ukrainian nationalists. To Maria's shock, the local Resistance unit is commanded by her older brother, Tomek-who she thought was dead. He is now a "Silent Unseen," a special-operations agent with an audacious plan to resist a new and even more dangerous enemy sweeping in from the East. When Tomek disappears, Maria is determined to find him, but the only person who might be able to help is a young Ukrainian prisoner and the last person Maria trusts-even as she feels a growing connection to him that she can't resist.
