Sydney, Australia, 1951. Near death, 14-year-old James Harrison received a transfusion of blood that saved his life. Here Julian Guthrie tells the gripping tale of the race to cure Rh disease, a blood disorder that causes a mother's immune system to attack her own unborn child. The story is anchored by two very different men on two continents: Dr. John Gorman in New York, who would land on a brilliant yet contrarian idea, and an unassuming Australian whose almost magical blood—and his unyielding devotion to donating it—would save millions of lives.
