When the author's sixteen-year-old daughter asked about testosterone injections and chest surgery, her immediate reaction was to slow down the speeding train about to rip her daughter away. What loomed like a permanent loss, a death for her, felt like a long-awaited birth for her child. My Daughter He: Transitioning With Our Transgender Children, describes the interior journey one mother took to let go of her beloved daughter so she could welcome her son. Based on the author's research in the field, the book also brings together the necessary information parents need to aid in the decision-making process while raising their gender nonconforming or transgender child. Offering concrete information for parents as well as reflections on what the author got right and what she wishes she did differently will help other parents on a similar path.
