In 1698, Jonathan Harker and Captain Matthew Ward return to Boston—heroes in rumor, haunted men in truth. After surviving witches, spirits, and the deadly Flying Heads, the King’s top investigators hope for peace. But peace ends the moment a forged letter lures them across the sea… straight into the hands of the most feared pirate on earth: Captain William Kidd.
Dragged into Kidd’s ruthless scheme to protect a hidden fortune, Harker and Ward are forced to design a labyrinth beneath a cursed island—one guarded by ancient powers that should never be awoken.
