Massachusetts in the Year of the Lord 1695: Gideon Jacobs and Caine Hopkins are the most feared witchfinders in all of New England. Accompanied by Fear-God Moody, former pirate turned torture master and executioner, they travel from town to town to hunt down witches and fight evil, armed with rapier, pistols and unwavering faith.
Their most elusive quarry is eighteen-year-old Matthew Goodson, their erstwhile apprentice, who eloped with the condemned witch Grace Pankhurst. In their mad flight across New England, Matthew and Grace face down menaces both human and supernatural, all the while trying to stay one step ahead of the witchfinders and the gallows.
