Sixteen-year-old Rachel Abramson will do anything to protect her friends and family. It's a tall order for a Jewish girl in Nazi-occupied Denmark, but Rachel is no ordinary girl. She has the ability to erase people's memories, making German soldiers forget her face or easing her friends' grief over lost loved ones.

When the Danish resistance attempts to smuggle Jews to safety in neutral Sweden, her sister is forced to stay behind. Rachel delays her own escape to look after her on her own, but they are caught and deported to the Terezin ghetto in Czechoslovakia.

There, Rachel is confronted with more fear and grief than she could ever erase, and she must find a different way to protect the people she loves if they are going to make it home alive.
