Poland, 1944. After the Soviet liberation of Lwów from Germany, the city remains a battleground between resistance fighters and insurgent armies, its loyalties torn between Poland and Ukraine.

Seventeen-year-old Tolya Korolenko is half Ukrainian, half Polish, and he joined the Soviet Red Army to keep himself alive and fed. When he not-quite-accidentally shoots his unit's political officer in the street, he's rescued by a squad of Ukrainian freedom fighters. They might have saved him, but Tolya doesn't trust them. He especially doesn't trust Solovey, the squad's war-scarred young leader, who has plenty of secrets of his own.

Then a betrayal sends them both on the run. And in a city where loyalty comes second to self-preservation, a traitor can be an enemy or a savior—or sometimes both.
