‘I want you to make a promise to me that you will always take care of your sisters. That you will always be there for one another. That you will not allow anyone to take you away from each other, ever. Do you understand?’ 

When they are little girls, Cibi, Magda and Livia make a promise to their father – that they will stay together, no matter what. Years later, at just fifteen, Livia is ordered to Auschwitz by the Nazis. Cibi, only nineteen herself, remembers their promise and follows Livia, determined to protect her sister, or die with her. Together, they fight to survive through unimaginable cruelty and hardship. 

 Magda, only seventeen, stays with her mother and grandfather, hiding out in a neighbour’s attic or in the forest when the Nazi militia come to round up friends, neighbours and family. She escapes for a time, but eventually she too is captured and transported to the death camp. 

 In Auschwitz-Birkenau the three sisters are finally reunited and, remembering their father, they make a new promise, this time to each other: that they will survive.
