Before he left for Afghanistan, Pat Tillman wrote a letter to his wife, Marie. A 'just in case' letter that she should read should the worst happen. Then, in April 2004, Marie's worst fears came true when Pat was killed in action. In the days and weeks that followed his letter became Marie's lifeline. His words helped her navigate a world she could no longer share with her husband. In The Letter, Marie shares for the first time about her journey to remake her life after Pat's death. Her story will be an encouragement to anyone whose life has taken an unexpected turn, and anyone who struggles to find their way back to normal life after a tragedy.
