Estimated to occur once in every 15,000 births, Prader-Willi Syndrome is a rare genetic disorder that includes features of cognitive disabilities, problem behaviors, and, most pervasively, chronic hunger that leads to dangerous overeating and its life-threatening consequences. Insatiable: A Prader-Willi Story and its companion comic book, Ultra-Violet: One Girl’s Prader-Willi Story, draw on dozens of intensive interviews to offer insight into the world of those struggling with Prader-Willi Syndrome. Both books tell the fictional story of Violet, a vivacious young girl born with the disorder, and her family, who— with the help of experts—will not give up their quest to give her a healthy and happy life.
