Into the Wild meets Red Notice, Wall Street Journal reporter Brett Forrest's extraordinary Lost Son uncovers the riveting story of Billy Reilly, a seemingly innocent American who was enlisted by the FBI to develop intelligence, and then disappears during a mysterious trip to Ukraine--a situation that tore his family apart as they sought answers from both US and Russian officials. Through meticulous reporting, Forrest deftly unveils the complex realities of America's national security apparatus through one family caught in its crosshairs, and masterfully exposes, in rich and shocking detail, the truth behind the young man's disappearance against all odds.
