Amanda McCrina’s Traitor is a tightly woven thrill ride exploring political conflict, deep-seated prejudice, and the terror of living in a world where betrayal is a matter of life or death. “Alive with detail and vivid with insight, Traitor is an effortlessly immersive account of a shocking and little-known moment in the turbulent history of Poland and Ukraine—and ironically, a piercing and bittersweet story of unflinching loyalty. I think Tolya has left my heart a little damaged forever.” —Elizabeth Wein, #1 New York Times bestselling author of Code Name Verity and The Enigma Game.
