After 68 -year-old David Granger crashes his BMW, medical tests reveal a brain tumor that he readily attributes to his wartime Agent Orange exposure. He wakes up from surgery repeating a name no one in his civilian life has ever heard - that of a Native American soldier whom he was once ordered to discipline. David decides to return something precious he long ago stole from the man he now calls Clayton Fire Bear. It might be the only way to find closure in a world increasingly at odds with the one he served to protect. It might also help him finally recover from his wife's untimely demise.

As David confronts his past to salvage his present, a poignant portrait emerges: that of an opinionated and goodhearted American patriot fighting like hell to stay true to his red, white, and blue heart, even as the country he loves rapidly changes in ways he doesn't always like or understand. Hanging in the balance are Granger's distant art-dealing son, Hank; his adoring seven-year-old granddaughter, Ella; and his best friend, Sue, a Vietnamese-American who respects David's fearless sincerity.

Through the controversial, wrenching, and wildly honest David Granger, Matthew Quick offers a no-nonsense but ultimately hopeful view of America's polarized psyche. By turns irascible and hilarious, insightful and inconvenient, David is a complex, wounded, honorable, and ultimately loving man. The Reason You're Alive examines how the secrets and debts we carry from our past define us; it also challenges us to look beyond our own prejudices and search for the good in our supposed enemies.
