I like books that have interesting characters and easy to follow plots. For example, Cormoran Strike, is a great character for me.
Michael Lewis is one of our great non-fiction writers. He has this amazing ability to take complex problems and make it understandable to the ordinary person. Moneyball joins his other books like "The Big Short" and "Liars Poker" that digs into the baseball industry, turns over the rocks and watches the insects scatter. Unlike the movie, which turned the book into a maudlin story of giving up money for being with his daughter, the book is a hard edge, no BS look at how his system of baseball team construction could be based on statistical analysis of player value. Although he was successful at portraying the success from the financial aspect, Lewis never really explores the consequential loss of the fun side of baseball. That is, some of the most enjoyable aspects of baseball like base stealing, sacrificing, hit and runs, squeeze plays etc. are virtually eliminated from ordinary play. Basically, Billy Beane turned his teams into no risk, maximum value only decisions that are really boring.
