I am on the System of the World by Neal Stephenson, it's the third in a trilogy entitled the "Baroque Cycle". Although he did say never to call it a trilogy, I hope he doesn't see this.
It's basically historical science fiction. He usues actual people (Newton, Hooke, Lebniz, Louis XIV, William of Orange, James Stuart, Queen Anne, etc) combined with people of his own creation that interact with them.
It tells a great story as well as describes the nature of money, and kind of shows in her own belief why the most likely smartest man in the world decided to run the Mint.
It also has government spys, the Solomonic Gold, Alchemy, the prototype computer, as well as swashbuckling adventures, financial schemes, and pitched battles across Europe as well as criminal dealings on a large scale.
Oh and also reading The Master and Margarita. It's about the Devil going to Communist Russia during 1929 and what he does to those who don't believe in God.
