After the death of his wife Joy Davidman, C.S. Lewis—the scholar whose rational apologetics had brought many to Christian faith—found his own beliefs shattered by grief. This short book, originally published pseudonymously, records his anguished wrestling with loss. Lewis had met Joy, an American writer, late in life; their marriage, though brief, brought him unexpected happiness. Her death from cancer left him questioning everything he had taught about suffering and providence. The entries move through stages of grief without following any neat progression: anger at God gives way to resignation, which collapses back into rage, which yields to tentative hope. Lewis is mercilessly honest about his own emotional states, including thoughts that seem to contradict his published convictions. He asks why God, who seemed so present before, now feels absent when needed most. The book's power comes from watching a formidable intellect grapple with experiences that resist intellectual resolution. Lewis eventually finds his way to a chastened faith, but not through argument—rather through exhaustion of alternatives and intimations of Joy's continued existence. This remains one of the most honest accounts of grief ever written, valuable to anyone who has loved and lost regardless of their religious commitments.
