At the pinnacle of a soaring career in the U.S. Army, Lt. Col. Mark M. Weber was tapped to serve in a high-profile job within the Afghan Parliament as a military advisor. Weeks later, a routine physical revealed stage IV intestinal cancer in the thirty-eight-year-old father of three. When Weber realized that he was not going to survive this final tour of combat, he began to write a letter to his boys, so that as they grew up without him, they would know what his life-and-death story had taught him. This book is that letter. And it’s not just for his sons. It’s for everyone who can use the best advice a dying hero has to offer.
