In a steam-driven alternate 1963, the British Empire faces off against neo-Tsarist Russia in cold war over a divided former USA.
Pirate captain Karen Ahle is an upper-class Southern exile with a vendetta against the mercenaries who’d butchered her family nineteen years earlier.
Imperial Vice-Commodore Marcus Perry is a duty-focused, by-the-book career officer sworn to uphold the law.
They’d been on a collision course until Theron Marko, Luddite anarchist and Russian agent, showed up with his own agenda.
Now they have to work together. If they succeed, Perry’s name will be cleared and Ahle’s crew will live. If they fail, North America’s map will be redrawn… by the Tsar.
