Liar's Poker is a book by Michael Lewis that tells the story of his time working as a bond salesman on Wall Street in the late 1980s. The book is set against the backdrop of the financial industry's transition from a relationship-based business to a more cutthroat and quantitative industry.

Lewis began his career at Salomon Brothers, a prestigious investment bank, and quickly rose through the ranks to become a successful bond salesman. However, as he navigated the high-stakes world of finance, Lewis found himself immersed in a culture of greed and excess, where traders were willing to do whatever it took to succeed.

Throughout the book, Lewis provides a behind-the-scenes look at the inner workings of investment banks and the culture of financial trading. He describes the intense pressure and competitiveness of the trading environment, and the impact that it had on the people who worked in it.

The book takes its name from a high-stakes betting game that was popular among bond traders, in which players try to outmaneuver one another by bluffing and deception. The game serves as a metaphor for the culture of Wall Street, where traders engage in a constant battle to outsmart each other and make as much money as possible.

In addition to providing a glimpse into the world of finance, Liar's Poker is also a commentary on the larger economic and social changes taking place in the United States during the 1980s. The book explores the rise of Wall Street and the increasing influence of financial markets on the economy and society as a whole.
