The Power of Two

Inspired by their 2007 memoir, "The Power Of Two" offers an intimate portrayal of the bond between half-Japanese twin sisters Anabel Stenzel and Isabel Stenzel Byrnes, their battle with the fatal genetic disease cystic fibrosis (CF) and miraculous survival through double lung transplants. Defying all odds, Ana and Isa have emerged as authors, athletes and global advocates for organ donation, and their connection to the CF and transplant communities provides rare insight into the struggles — and overlooked joys — of chronic illness. The twins' receiving new lungs would have been unlikely in their mother's native country, Japan, where organ donation rates are strikingly low. At the crux of a rising movement to change laws and stigmas, Ana and Isa embark on a tour of Japan to inspire change in the hearts and minds of a culture resistant to transplantation.
