Martin started a fundraiser in June to raise money for his favorite charity, the Wild Spirit Wolf Sanctuary and Food Depot in Santa Fe, N.M. Two fans who donated $20,000 or more would win the honor of getting written into Martin's next book, The Winds of Winter, and seeing their character meet a brutal death. One Facebook employee and another fan won the grand prize.

Jack from the United Kingdom, 13, wrote a personal letter to the author along with the entirety of his pocket money, equaling about 153 pounds ($260). He said that wolves were his favorite animal and he would like to offer his money for a "gruesome, grizzly death."
