An act of defiance.
A statement of hope.
A crime punishable by death.

Making a birthday card in Auschwitz was all of those things. But that is what Zlatka did, in 1944, for her best friend, Fania. She stole and bartered for paper and scissors, secretly creating an origami heart. Then she passed it to every girl at the work tables to sign with their hopes and wishes for happiness, for love, and most of all—for freedom.

Fania knew what that heart meant, for herself and all the other girls. And she kept it hidden, through the bitter days in the camp and through the death marches. She kept it always.
