Reviews of his book include:

Bright sparks like Mr. Bookstaber ushered in a revolution that fuelled the boom in financial derivatives and Byzantine 'structured products.' The problem, he argues, is that this wizardry has made markets more crisis-prone, not less so. It has done this in two ways: by increasing complexity, and by forging tighter links between various markets and securities, making them dangerously interdependent. – The Economist

Like many pessimistic observers, Richard Bookstaber thinks financial derivatives, Wall Street innovation and hedge funds will lead to a financial meltdown. What sets Mr. Bookstaber apart is that he has spent his career designing derivatives, working on Wall Street and running a hedge fund. – The Wall Street Journal

In the book, he makes a simple point: The turmoil in the financial markets today comes less from changes in the economy--economic growth, for example, is half as volatile as it was 50 years ago--and more from some of the financial instruments (derivatives) that were designed to control risk. – The New York Times

I cannot recommend this book too highly. It is a clear exposition of what the combination of derivatives, leverage and hedge funds can do to the markets. In short, A Demon of our Own Design is a guide to the dangerous financial markets we have created for ourselves by the clever innovations of structured finance, derivatives, credit default swaps and other newfangled products that are a mystery to the ordinary investor and even plenty of the sophisticates in the investment business. To understand the demonic risks we're taking, read this book. – Forbes.com
