Six-year-old Gretl Schmidt is on a train bound for Aushwitz. Jakob Kowalski is planting a bomb on the tracks.
As World War II draws to a close, Jakob fights with the Polish resistance against the crushing forces of Germany and Russia. They intend to destroy a German troop transport, but Gretl s unscheduled train reaches the bomb first.
Gretl is the only survivor. Though spared from the concentration camp, the orphaned German Jew finds herself lost in a country hostile to her people. When Jakob discovers her, guilt and fatherly compassion prompt him to take her in. For three years, the young man and little girl form a bond over the secrets they must hide from his Catholic family.
But she can t stay with him forever. Jakob sends Gretl to South Africa, where German war orphans are promised bright futures with adoptive Protestant families so long as Gretl s Jewish roots, Catholic education, and connections to communist Poland are never discovered.
Separated by continents, politics, religion, language, and years, Jakob and Gretl will likely never see each other again. But the events they have both survived and their belief that the human spirit can triumph over the ravages of war have formed a bond of love that no circumstances can overcome.
