Sara Davidson will discuss her latest book, "The December Project: An Extraordinary Rabbi and a Skeptical Seeker Confront Life's Greatest Mystery" (2015, HarperOne), which recounts her two years of discussion with Rabbi Zalman Schachter-Shalomi, the acclaimed founder of the Jewish Renewal movement who died in 2014, about life, old age and human mortality. During their time together, Davidson was nearly killed by a suicide bomb and Schachter-Shalomi faced a steep decline in health. They created strategies to deal with pain and memory loss and found tools to cultivate fearlessness and joy — at any age. A book signing will follow Davidson's talk.
