The subtitle is Warren Buffett and the Business of Life. Is it massive? Yes. Does it contain numerous revelations about his childhood, his "slight obsession" with trains, his love of collecting, and his sex life? Yes. Is it well written and well researched? Yes. Does it cover many financial episodes (most of all Salomon Brothers) and famous characters? Yes. Is it number one on Amazon? Yes. Does it contain analytic depth? No. Did I like it? Yes, but for a return which is mostly biographical in nature, it’s a lot of detail to wade through.
