On April 15, 2013, Rebekah Gregory and her five-year-old son waited at the finish line of the Boston Marathon to support a friend who was running. When the blasts of terrorists’ homemade bombs packed with nails and screws went off three feet away, Rebekah’s legs took the brunt of the blast, protecting her son from certain death. Eighteen surgeries and sixty-five procedures later, her left leg was amputated.
