Bitter Sweet, How Sorrow and Longing Make Us Whole

Susan Kane's new book is called Bitter Sweet, How Sorrow and Longing Make Us Whole. It explores the idea that two conflicting labels or emotions can both be true. In her 2012 book Quiet, she looked at the power of introverts in a world that can't stop talking. "There is so much nuance to the human experience," says Kane.
