It was a call FBI informant and former Army sniper Joe Moore never expected to get. He’d already infiltrated the Ku Klux Klan once before, and his contributions prevented an assassination attempt targeting then-presidential candidate Barack Obama. Moore nearly lost his life in the process. But now, the FBI needed Moore’s help once again. In Moore reveals the astounding true story of how he became one of the most entrenched and valuable undercover agents in the FBI’s history. Gripping, told with astonishing detail, this heart pounding and darkly propulsive memoir vividly recounts how he infiltrated the “Invisible Empire” at the highest levels—not once, but twice—becoming a Grand Knighthawk, overseeing security, defense, and internal communications for the domestic terrorist group across Florida and Georgia. Moore makes clear how the seeds of violence and hate spawned the tragedy in Charlottesville, the failed January 6 Capitol coup, and the growing threat posed by extremist militias—including the Oath Keepers, Proud Boys, Three Percenters, and others. Going undercover, Moore discovered the shocking connections between the KKK and law enforcement across Florida—police officers, prison guards, and sheriff’s deputies who all belonged to the Klan—and eventually exposed the terrifying presence of right-wing extremists throughout law enforcement today. Moore reflects on the steep personal costs of immersing himself in the Klan’s racist ideology and twisted rituals—and its effect on himself and his family—while secretly providing the FBI with invaluable information on the Klan’s inner workings, murderous plots, and plans for civil war. With a foreword by Congressman Jamie Raskin and illustrated with 8-pages of color photos, is a comprehensive and unprecedented look at a growing threat in America and an urgent call-to-action—because ultimately, the answers to healing the divides in this country lie in its perilous history.
