The gripping and heroic firsthand account—like American Sniper mixed with a real-life version of Die Hard—by an off-duty special forces soldier who battled against a terrorist attack for twenty-two hours, and saved scores of American, Kenyan, and European lives.

After an otherwise ordinary morning of training with his firearms, British SAS soldier Chris Craighead was just beginning to relax in his new home in the bustling city of Nairobi, Kenya. Then the phone rang.

It was a friend, a former British soldier. In the background, Chris heard gunfire. The friend gave the address of an upscale DusitD2 hotel and office complex in Nairobi’s affluent Westgate neighborhood. He said it was under attack.

Within minutes, Chris was in his pickup truck with his weapons case in the back seat, racing to the scene. For the next twenty-two hours, he relied on his nearly three decades of elite military training to win a deadly game of hide-and-seek with a unit of ethnic Somali terrorists who had already detonated one suicide bomb and were intent on killing as many other people as possible.

Told in white-knuckle, minute-by-minute detail, One Man In is an unforgettable true story of heroism from a special forces soldier who happened to be in the right place at the right time—and decided to act.
