In April 1992 a young man from a well-to-do family hitchhiked to Alaska and walked alone into the wilderness north of Mt. McKinley. His name was Christopher Johnson McCandless. He had given $25,000 in savings to charity, abandoned his car and most of his possessions, burned all the cash in his wallet, and invented a new life for himself.

On October 12, 1972, a plane carrying a team of young rugby players crashed into the remote, snow-peaked Andes. Out of the 45 original passengers and crew, only 16 made it off the mountain alive. For 10 excruciating weeks, they suffered deprivations beyond imagining, confronting nature head-on at its most furious and inhospitable. And to survive, these men and women not only had to keep their faith; they had to make an impossible decision: Should they eat the flesh of their dead friends?

Joe Simpson, with just his partner, Simon Yates, tackled the unclimbed West Face of the remote 21,000-foot Siula Grande in the Peruvian Andes in June of 1985. But before they reached the summit, disaster struck. A few days later, Simon staggered into Base Camp, exhausted and frostbitten, to tell their non-climbing companion that Joe was dead. For three days he wrestled with guilt as they prepared to return home. Then a cry in the night took them out with torches, where they found Joe, badly injured.

From 1999 to 2009, U.S. Navy SEAL Chris Kyle recorded the most career sniper kills in United States military history. The Pentagon has officially confirmed more than 150 of Kyles kills (the previous American record was 109), but it has declined to verify the astonishing total number for this book. Iraqi insurgents feared Kyle so much they named him al-Shaitan (“the devil”) and placed a bounty on his head. Kyle earned legendary status among his fellow SEALs, Marines, and U.S. Army soldiers, whom he protected with deadly accuracy from rooftops and stealth positions.

In his early 20s, Curtis Jackson, known as 50 Cent, rose to the heights of fame and power in the cutthroat music business. A decade ago, the multi-platinum selling rap artist decided to pivot. His ability to adapt to change was demonstrated when he became the executive producer and star of Power, a high-octane, gripping crime drama centered around a drug kingpin's family. The series quickly became "appointment" television, leading to Jackson inking a four-year, $150 million contract with the Starz network - the most lucrative deal in premium cable history.
