Title: In the Country of the Blind
Description: In the nineteenth century, a small group of American idealists managed to actually build Charles Babbage's Analytical Engine and use it to develop Cliology, mathematical models that could chart the likely course of the future. Soon they were working to alter history's course as they thought best.

By our own time, the Society has become the secret master of the world. But no secret can be kept forever, at least not without drastic measures. When her plans for some historic real estate lead developer and ex-reporter Sarah Beaumont to stumble across the Society's existence, it's just the first step into a baffling and deadly maze of conspiracies.
