On February 10, 1918, John Power woke to the sound of bells and horses' hooves. He was sharing a cabin near the family mine with his brother Tom and their father Jeff; hired man Tom Sisson was also nearby. Then gunfire erupted, and so began the day when the Power brothers engaged the Graham County Sheriff's Department in the bloodiest shootout in Arizona history. Now Thomas Cobb has taken up the story in this powerful and meticulously researched non-fiction novel.
