Happily married and teaching history at the University of Oxford, Sarah Williams had credentials, success, and knowledge. It took someone who would never have any of these things to teach her what it means to be human. When her unborn daughter Cerian was diagnosed with a lethal skeletal dysplasia, Sarah knew they would only have a few fleeting months together. But in that time, Cerian would transform Sarah's understanding of beauty, worth, and the gift of life.
