When the Gestapo haul Izaak and Maria Szpilmann away to Ravensbrück, their twin infants are left behind to die. Instead, neighbors Gustaw and Ròsa Dudek rescue the babies and flee occupied Poland. They are never heard from again.
Maria Szpilmann has survived Ravensbrück, Auschwitz, and Bergen-Belsen. Now she is grandmother to Madeline Sommers, a young journalist who, despite the odds, passionately clings to the belief that the lost twins are still alive. Her single-minded mission is to find them -- and reunite them with her failing grandmother -- before it's too late.
