In November 1999, Joan Didion began seeing a psychiatrist because, as she wrote to a friend, her family had had “a rough few years.” She described the sessions in a journal she created for her husband, John Gregory Dunne. Didion’s journal was crafted with the singular intelligence, precision, and elegance that characterize all of her writing. It is an unprecedented, intimate account that reveals sides of her that were unknown, but the voice is unmistakably hers — questioning, courageous, and clear in the face of a wrenchingly painful journey.
