On a clear night in late June 2005, four U.S. Navy SEALs left their base in northern Afghanistan for the mountainous Pakistani border. Their mission was to capture or kill a notorious al Qaeda leader known to be ensconced in a Taliban stronghold surrounded by a small but heavily armed force. Less then twenty-four hours later, only one of those Navy SEALs remained alive.

This is the story of fire team leader Marcus Luttrell, the sole survivor of Operation Redwing, and the desperate battle in the mountains that led, ultimately, to the largest loss of life in Navy SEAL history. But it is also, more than anything, the story of his teammates, who fought ferociously beside him until he was the last one left. Over the next four days, badly injured and presumed dead, Luttrell fought off six al Qaeda assassins who were sent to finish him, then crawled for seven miles through the mountains before he was taken in by a Pashtun tribe, who risked everything to protect him from the encircling Taliban killers.

Luttrell takes us, blow-by-blow, through the brutal training of America's warrior elite and the relentless rites of passage required by the Navy SEALs and transports us to a monstrous battle fought in the desolate peaks of Afghanistan.
