Money Stuff is great, and explains things quite well, generally, but I think for a beginner in the field it presupposes too much. It dwells on the amusing arcana, the esoteric warts of the system often, that you only appreciate once you have a certain base level understanding of the industry.
Lastly, it’s fairly focused on the investment banking side of things (derivatives, capital markets, IPOs, the finance industry), not so much on the monetary system, macro, and institutions.
On banking and banking regulation, making a case for higher capital (=equity) requirements for banks, The Bankers' New Clothes: What's Wrong with Banking and What to Do about It by Anat Admati and Martin Hellwig is a good read [1].
I can’t think of a good book on money and the various theories about - if someone has a recommendation there, would be great.
