I was captivated by The Snowball: Warren Buffett and the Business of Life by Alice Schroeder. It's amazing that Schroeder was given the access that she was, and the result is a truly fascinating book about a great investor and businessman.
It's not a snow job by any means -- Buffett is a man with warts, and Schroeder does her best to show the real man -- sometimes cheap, selfish, and self-centered. Far from the legend of Warren Buffett, Schroeder, shows us an investor who worked very hard, was brilliant, and was lucky enough to get away with making a few major mistakes.
I found the book inspiring, both personally and professionally. The book made me want to save more, and want to invest my savings.
