A rebel and risk-taker from childhood, John McCain-son and grandson of admirals-nevertheless chose to follow the traditional path marked out for him in the military. Nearly six years in a North Vietnamese prison tested his resolve and proved his extraordinary resilience and will to survive. Coming to Congress, McCain found that making his way in politics demanded a different set of survival skills, and he grew accustomed to the corridors of power while striving to keep his independence. This lively biography traces McCain's unlikely ascent to the verge of attaining the nation's highest office while never ceasing to challenge himself and others to "serve a cause greater than self-interest."
