While her physician-parents are working in Africa, eleven-year-old Zelda is living with her grandfather, eighty-year-old Holocaust-survivor Felix Salinger, in Australia, when a disaster leads them both to deal with unresolved feelings about the first Zelda, Felix's childhood friend.

In early 1940s Poland, ten-year-old Felix and his friend Zelda escape from a cattle car headed to the Nazi death camps and struggle to survive, first on their own and then with Genia, a farmer with her own reasons for hating Germans.
