Congresswoman Gabrielle Giffords and her husband, astronaut Mark Kelly, showed Americans how optimism, an adventurous spirit, and a call to service can help change the world. Their arrival in the spotlight came under the worst of circumstances. On January 8, 2011, while meeting with constituents in Tucson, Arizona, Gabby was the victim of an assassination attempt that left six people dead and thirteen wounded. Gabby was shot in the head; doctors called her survival "miraculous." As the nation grieved and sought to understand the attack, Gabby remained focused on her against-all-odds recovery. Mark spent every possible moment by her side, as he also prepared for his final mission as commander of Space Shuttle Endeavour. Now, as Gabby's health continues to improve, the couple is sharing their remarkable untold story, an unflinching look at the overwhelming challenges of brain injury, the painstaking process of learning to communicate again, and the responsibilities that fall to a loving spouse who wants the best possible treatment for his wife.
