The infamous Sonny Barger once declared that the Hells Angels would never be infiltrated. Running with the Devil chronicles the story of the ATF sting and the two undercover agents who risked their lives to prove him wrong. For two years, they posed as members of a Mexican renegade motorcycle club, earning the trust and respect of the vicious Arizona Hells Angels.

Their work led to the shocking 2003 bust in which ATF agents arrested fifty people and seized 650 guns, 30,000 rounds of ammunition, and more than 100 explosive items—including grenades and napalm.

Writing in cooperation with ATF agents, most of whom remain undercover today, Kerrie Droban follows the perilous mission up through the ensuing court case and jail sentences. Along the way, she provides a startling—and unprecedented—expose on the treacherous inner workings of the Hells Angels brotherhood.
