"Grace Cahill was never like other people--even when she was a kid. When she was 13, she started taking flying lessons. When she was 14, she convinced her father to buy her a small plane. When she was 15, she wrote to President Franklin D. Roosevelt and volunteered to fight in World War II. Grace was always off exploring somewhere and had little time for ordinary family and friends. Her favorite person was her baby brother, Fiske Cahill. She was heartbroken when he disappeared in 1962."
