Host Audrey Coleman interviews heart donor recipient and author Pete Radigan. Pete was in end-stage heart failure and unsure whether he would live before receiving a transplant. His book, "Tragedy to Triumph -- The Story of Tom's Heart," was co-authored with Janet Mauk, the mother of his heart donor. It tells the donor family's story of finding purpose through organ and tissue donation following tragic loss, and the recipient's story of finding hope for a new life.
