"The book that America needs right now."--Tom Brokaw, journalist and author of The Greatest GenerationWhen Marine sniper Jake Wood arrived in the States after two bloody tours in Iraq and Afghanistan, he wasn't leaving war behind him--far from it. Ten years after returning home, Jake's unit lost more men to suicide than to enemy hands overseas. He watched in horror as his best friend and fellow Marine, Clay Hunt, plunged into depression upon returning, stripped of his purpose, community, and sense of identity. Despite Jake's attempts to intervene, Clay died by suicide, alone. Reeling, Jake remembered how only one thing had given Clay a measure of hope: joining him in Haiti on a ragtag mission to save lives immediately following the 2010 earthquake. His military training had rendered him unusually effective in high-stakes situations. What if there was a way to help stricken communities while providing a new mission to veterans? In this inspiring memoir, Jake recounts how, over the past 10 years, he and his team have recruited over 130,000 volunteers to his disaster response organization Team Rubicon. Racing against the clock, these veterans battle hurricanes, tornados, wildfires, pandemics, and civil wars, while rediscovering their life's purpose along the way.Once a Warrior provides a gut-wrenching account of the true cost of our Forever Wars--and more importantly, a glimpse of what might become of America's next greatest generation.
