Thousands of years in the future, the division between the sexes is entrenched, turning to warfare. Many technologies are lost and much history forgotten, but gynogenesis (by which two women may have a child) is becoming the scientific foundation for the Empire of Her Majesty, Berenice I. Amidst the haunted marshes of outlying Essex, the routine and romance of homes and offices in the Surrey heartland, and the crumbling feudal heritage of Lundin town, the action unfolds like the panorama from a stagecoach window. Jane is a sixteen-year-old civil servant under Her Majesty. Sent to audit the spoils of battle, she falls for Captain Modesty Clay, precipitating a maelstrom of events that force her to grow up fast, and in which she catches the eye of the Empress herself.
