At just 15, Johnathan Morin received a devastating diagnosis: metastatic Ewing Sarcoma. But he didn’t ask “Why me?” — he simply said, “Tell me what I need to do.” Known as “Johnny Rocket,” this old soul with a competitive streak fought cancer with courage, humor, and grit. He doubled up on school, made the honor roll, took his dream trip to Hawaii, and dreamed of becoming a doctor to help other kids like him. Even as cancer returned again and again, he kept living — cheering on the Red Sox, riding his motorcycle, and filling every moment with purpose. This is the story of a brave young man who taught everyone what it means to live with heart.
