Key Is Lost — Ida Vos

What would it be like to lose your home, your family, and even your name?

Eva and Lisa Zilverstijn find out. When they go into hiding from the Nazis during World War II, they lose everything but each other.

As they move from attic to attic, Eva and Lisa must rely on their courage, their imaginations, and the compassion of strangers to survive.

Based on the author's own experiences in Wartime Holland, The Key Is Lost is a moving, understated story about the will to live and how two girls triumph against tremendous odds.
