Poland, 1944. After the Soviet liberation of Lwów from Germany, the city is a battleground, its loyalties torn between Poland and Ukraine. Tolya is half-Ukrainian, half-Polish, and he joined the Soviet Red Army just to stay alive. When he shoots his political officer in the street, he's taken in by a squad of insurgent Ukrainians. Tolya doesn't trust them and especially doesn't trust Solovey, the squad's young war-scarred leader. He doesn't know just how well Solovey understands the cost of looking out for life over loyalty. Then a betrayal sends both on the run.

Traitor is an action-packed thriller about a world where loyalty begets lying, traitors pass as saviors, and betrayal is a matter of life or death.
