All the King's Men is the story of the rise and fall of Willie Stark, a character based on Huey Long, a 1930's Lousiana politician who sells his scruples for political power. The book is narrated by Stark's right-hand man, Jack Burden, whose moral compass never wavers. It's an intoxicating story about power, the lengths humans will go to gain it, and the damage that it does them.
