Disguise: A Novel

1945. At the end of the Second World War, a young mother loses her two-year-old boy in the bombings of Berlin. She flees to the south, where her father finds among the refugee trains a young foundling of the same age to replace his grandson. He makes his daughter promise never to tell anyone, including her husband—still fighting on the Russian front—that the boy is not her own. Nobody will know the difference.
