explain the protagonist.

Hannah Stern is the protagonist of the story. Hannah is a young Jewish girl who lives with her family in New Rochelle, NY. She is disinterested in, and even embarrassed by, her Jewish heritage and family. During a Seder dinner she is suddenly transported to Poland in 1942 where she inhabits the life of her own distant relative, Chaya Abramowicz, who sacrifices herself to save Rivka. Through this process Hannah comes to appreciate her own history and that of her family.
