The devil's arithmetic

by Jane Yolen

Hannah thinks tonight's Passover Seder will be the same as always. Little does she know that this year she will be mysteriously transported into the past where only she knows the horrors that await. Hannah resents the traditions of her Jewish heritage until time travel places her in the middle of a small Jewish village in Nazi-occupied Poland. Hannah resents stories of her Jewish heritage and of the past until, when opening the door during a Passover Seder, she finds herself in Poland during World War II where she experiences the horrors of a concentration camp, and learns why she-- and we--need to remember the past.
