The Excellent book. Michael Lewis has written from the perspective of a financial insider for more than 20 years. His first book, Liar's Poker, was a warts-and-all account of Wall Street culture in the 1980s, when Lewis worked at the investment bank Salomon Brothers. Everything Lewis has touched since has turned to gold, and The Big Short seems to be another of those books, combining an incendiary, timely topic with the author's solid, insightful, and witty investigative reporting.
