On the last hot day of summer in 1992, gunfire cracked over a rocky knob in northern Idaho, just south of the Canadian border. By the next day three people were dead, and a small war was joined, pitting the full might of federal law enforcement against one well-armed family. Drawing on extensive interviews with Randy Weaver's family, government insiders, and others, Jess Walter traces the paths that led the Weavers to their confrontation with federal agents and led the government to treat a family like a gang of criminals.

This is the story of what happened on Ruby Ridge: the tragic and unlikely series of events that destroyed a family, brought down the number-two man in the FBI, and left in its wake a nation increasingly attuned to the dangers of unchecked federal power.
