When Mark Kelly and Gabrielle Giffords were dating, Gabby did most of the talking. In their book, Gabby: A Story of Courage and Hope, Kelly describes her as "the most positive person I'd ever met."
Their dynamic shifted dramatically in January of 2011, when a gunman shot and killed six people at a community event in Tucson and injured more than a dozen others, including Congresswoman Giffords, who was shot in the head.
Doctors have called her subsequent recovery miraculous, but speaking is now a challenge for Giffords and Kelly does most of the talking. As Giffords continues to recover, he watches his wife face pain and frustration with remarkable courage, and hope.
In their book, the couple shares their low points, Giffords' remarkable progress and the memories that inspire them each day. Kelly talks with NPR's Neal Conan about their journey back from traumatic brain injury, and what lies ahead.
