In 'Lit," the long-awaited sequel to her New York Times bestselling memoirs "The Liars Club" and "Cherry," Mary Karr chronicles her descent into the inferno of alcoholism and madness, and her astonishing resurrection. A recollection of her struggle to come to terms with her Christian faith after years as an agnostic that explores the relationship between spirituality and substance abuse and depression, Lit is also about getting drunk and getting sober; becoming a mother by letting go of a mother; and learning to write by learning to live.
