The Girl from the Train

This story spans 15 tragic and heartbreaking years during and after World War 2.
6 year old Gretl and her older sister Elza are made to jump from a train bound for Aushwitz by their grandmother who hopes to save them from the horrors of the concentration camp. Just after they get off, the train is ripped to pieces by bombs. Gretl and Zelda are now utterly alone in the world. Orphaned, thirsty, starving, and alone. They are discovered by Jakob who takes them home, but there is very little room for them and Zelda is terribly sick.
As a fan of historical fiction I will say that this is a must read for any other fan. The sheer bravery and strength of character that Gretl shows in the face of suffering such tragic loss in such brutal times had me cheering her on every step of the way
