A great book. It is very comprehensive and written in a simple way (regarding the complexity of the themes it deals with). The investigation is very objective, it uses sound theoretical analysis and different mathematical models (which he explains in relatively simple terms), contrasting them with the historical evidence and empirical data. It treats the history and development of money (from commodity money to fiat money), and monetary institutions, doing an exceptional analysis of the gold standard, its costs and benefits. It also analyzes the role of Central Bank's in money and banking, and uses various models used to try to explain the Central Bank's behavior, according to different goals that Central Banks may have. Finally, it discusses alternative monetary proposals from Friedman to Yeager, with its pros and cons. In conclusion, a great book to update and deepen your knowledge about money and banking.
