Listened to the audio book, which was a great experience because of McCullough engaging writing style and soothing narration. McCullough traces the entire course of Truman's life from his pioneering ancestors to death. I think he could've devoted more time to Truman's presidency, specifically the criticisms about corruption in his administration, his experience at the little White House, and relationship with Eisenhower. Ultimately it was a strong biography that brought Truman's character and his era to life and made me admire Truman as a person and President even more than I already did.
