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. Over the next two years, he would fight a desperate battle he wasn’t trained for, with his wife and boys as his reluctant but willing fighting force.

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—about courage and fear, challenge and comfort, words and actions, pride and humility, seriousness and humor, and viewing life as a never-ending search for new ideas and inspiration.
