The New York Times bestselling account of the most extensive undercover operation inside a criminal motorcycle gang in American history.

When veteran law-enforcement officer and lifelong motorcycle lover William Queen penetrated the San Fernando chapter of the notorious Mongols, he was at the mercy of psychopaths who sought to have him prove his fealty by any means necessary, from selling and doing drugs to arms trafficking, driving getaway cars and, in one shocking instance, stitching up the face of a Mongol ‘ol’ lady’ after a brutal beating at the hands of her boyfriend.

Yet despite the constant criminality of the gang, Queen came to see the genuine camaraderie they shared. When his lengthy undercover work totally isolated Queen from his relatives and friends, the Mongols felt like the only family he had left. Under and Alone is a breathless, adrenalin-charged read that puts you on the street with some of the most dangerous men in America.
