The Informational Role of Prices Book

Reasonable treatment of monetary economics in a textbook way that could be used to accompany a course. Each chapter develops an idea about monetary economics and presents a model that can illustrate the point. The core model, however, is an overlapping generations model which is no longer the state-of-the-art nowadays. In fact, there is now a general perception that it is not overlapping generations that explain the need for money, with models of double-coincidence-of-wants taking the lead.

Generally, I would say this is an interesting book for an undergraduate level, but if you want to understand more about monetary economics, you will have to proceed to other kinds of models. Specifically, I would advise you to read about the Fiscal Theory of the Price Level which for me is really the most coherent theory around.
