The Devil's Arithmetic by Jane Yolen

When Hannah opens the door during Passover Seder to symbolically welcome the prophet Elijah, she suddenly finds herself in the unfamiliar world of a Polish village in the 1940s.

The Nazi soldiers have come to take the villagers away, and only Hannah can guess where they are going. Ages 12 and up.   Publication Date: 1/1/1990Binding: Paperback
