Author Susan Kushner Resnick will be at the New England Mobile Book Fair at 2 p.m. Saturday to promote her new book, “You Saved Me, Too: What a Holocaust Survivor Taught Me About Living, Dying, Fighting, Loving, and Swearing in Yiddish,” which chronicles her relationship with Aron Lieb after they met at a Jewish community center 15 years ago. “You Saved Me, Too” is the story of how two people shared the hidden parts of themselves and created a bond that was complicated and challenging, but ultimately invaluable. The book alternates between his history, their developing friendship, and a health crisis that may force them to part. Resnick will take part in a reading and discussion, as well as sign copies of her book, at the store, 82 Needham St. in Newton Highlands. For more information, visit www.nebookfair.com.
