It is the story of Daniel Waterhouse, fearless thinker and conflicted Puritan, pursuing knowledge in the company of the greatest minds of Baroque-era Europe, in a chaotic world where reason wars with the bloody ambitions of the mighty, and where catastrophe, natural or otherwise, can alter the political landscape overnight.
It is a chronicle of the breathtaking exploits of "Half-Cocked Jack" Shaftoe - London street urchin turned swashbuckling adventurer and legendary King of the Vagabonds - risking life and limb for fortune and love while slowly maddening from the pox.
And it is the tale of Eliza, rescued by Jack from a Turkish harem to become spy, confidante, and pawn of royals in order to reinvent Europe through the newborn power of finance.
