The New Buffettology was written by Mary Buffett, who at one time was the daughter-in-law of Warren Buffett. Warren Buffett holds the title of "World's Greatest Investor." In her book, Buffett goes into great details explaining the principles and strategies that Warren Buffett use to invest in businesses or individual stocks. She is a excellent communicator by taking a subject that can be very complex and explaining it in a manner that's easily understood. This is an outstanding book for those desiring to learn how Warren Buffett thinks and invests. The book lived up to my expectations with the information that it provided but also far exceeded them. Again, this is an outstanding book!
