This was a really interesting book but it is not going to be for everyone. As a historical biography, I really enjoyed it. If you aren't interested in the aspects pertaining to Freemasonry, you may find yourself skipping parts of this book. If you have an interest in alchemy, early medicine, the occult, or french history, then you will probably find yourself thoroughly enjoying this book (or arguing with aspects of it from a different perspective). I deducted a star because in places, I really fell the argument fell flatter than it did in other parts. Overall, I liked it enough that I would buy it for my bookshelf and reread it.

This book is an excellent introductory novel into the Freemason world. Suppose to be a critique of the infamous Count Cagliostro, it ends up being a manual of Freemasonry throughout the ages. I'm actually surprised at the amount and how far in detail Faulks and Cooper reveal concerning this secret organization. Having studied the French Enlightenment period I was not all together surprised by the connection with Masonry during this period. Magic, sigils, and secret languages, after reading this book I'm viewing everything through a more critical or open eye. The book is wonderful for those with a fascination with alchemy and the mathematical power of the immortal Universe.
