The secret of their identities is the only thing keeping them safe.

Czechoslovakia, 1944. Hilda and Sheindy's quiet lives are overturned the day the Nazis march them out of their village home and onto a train bound for the unknown. Separated from their parents and five older siblings, the girls cling to each other for survival in their new reality—between the cold, lonely walls of Auschwitz.

Hilda knows that if they want to live, they will have to escape. So, when an opportunity presents itself, she makes a daring decision, risking both her life and her sister's in a bold move that will take them out of the Nazis' hands… and directly into the German countryside.

The sisters find themselves stranded in a foreign, enemy land, with no money to their name, no papers, and even worse—with incriminating Auschwitz tattoos prominent on their arms. Hilda and Sheindy know they will have to muster their every wit and ounce of courage if they ever want to live through the war and see their home again. The identities they take on as German orphans seeking shelter are the only thing keeping them safe–and the very thing that could send them straight back into the Nazis' deadly hands.

This heart-wrenching true story of two sisters' unbelievable survival against the odds speaks to the courage of the human heart and the unbreakable bond between sisters. Those who love Kelly Rimmer and Ellie Midwood will not be able to resist The Secret Orphan Sisters.
