In a gripping voice, Grace Larson dramatically recounts the tornado that destroyed her church on Palm Sunday, killing nineteen people and causing her to go into labor and give birth to a son. As Cole grows up, it becomes clear that he is just as dangerous and destructive as the storm he was born out of, a dark force of nature himself. With a mother's fierce love and profound guilt, Grace tries to see him as the man he is, and herself as the woman she could yet become.
