Cristina's son was about to embark on gender-affirming care that would likely cause infertility, when she realised the need to support both her child and the adult he would become, and give him the right to have children of his own. In doing so she discovered a future - where living your life authentically doesn't mean giving up your fertility - that may be accessible to many, many more trans people in the coming years. Through interviews with trans thought leaders, letters to her son, and missives about the struggle for reproductive rights of trans people, as well as practical advice for parents, Cristina weaves together a tapestry of voices from the trans community to tell a story that has never been told before -- of transformation, and hormones, and hope. An amazing resource for parents of children undergoing gender affirming care, and a beautiful meditation on the euphoria and challenge of transition
