I Want You to Know We Are Still Here by Esther Safran Foer

After learning that her father had a previous wife and daughter, both killed in the Holocaust, author Esther Safran Foer travels to Ukraine -- armed only with a black-and-white photo and a hand-drawn map -- to find answers: about her father's life before the war; how he had survived, and the family he'd left behind. 

I Want You to Know We Are Still Here is a riveting memoir of family, the Holocaust, and the search for truth.
