Focusing on the twentieth and twenty-first centuries, the book draws from scores of interviews to make its various points. Some, like the discussion with Susannah Heschel, the daughter of civil rights icon Rabbi Abraham Joshua Heschel, are enlightening. Others, like those with Heschel’s other family members, are less so.
