Welcome to Tremontaine, the prequel to Ellen Kushner’s beloved Riverside series that began with Swordspoint! A Duchess whose beauty is matched only by her cunning; her husband’s dangerous affair with a handsome scholar; a foreigner in a playground of swordplay and secrets; and a mathematical genius on the brink of revolution—when long-buried lies threaten to come to light, betrayal and treachery know no bounds with stakes this high. Mind your manners and enjoy the chocolate in a dance of sparkling wit and political intrigue.
