In June 2019, Green released a self-published autobiography titled "Hunter of Hope: A Life Lived Inside, Outside and On the Ropes." In it, he revisits his life as a teen in Guatemala, where, because of his alcoholic father's negligence, he was suffered years of sexual abuse by his father's friends. The golf course was a refuge from this abuse. He explains one reason for the book: "My plan has been simple: Use the adversity as my purpose and reason to live."
