After six years of self-imposed exile in the North, Queen Leslie of Valedorn returns to the capital—keeping a low profile—to attend a peace celebration. She discovers that her husband, Cedric, has seized absolute power as regent and is keeping a mistress, Margaret. Margaret, unaware of the Queen’s true identity, publicly humiliates her by labeling her a "Northern slut." Cedric, meanwhile, lavishes his mistress with royal treasury funds, lands designated for the Crown Prince, his daughter’s necklace, and even warhorses. Concealing her identity, Leslie orchestrates a calculated takedown, enlisting the aid of the Inquisition, the royal treasurer, King Tristan of a neighboring realm, and the Marquess of Holt. Together, they expose a web of betrayal involving Cedric and Leslie’s own close friend, Cecilia—uncovering embezzlement, poisoning, and a plot to incite a military coup. In the end, the villains are brought to a public trial; Leslie reclaims her throne, takes her place at the celebration, and enters into a mutual, chosen partnership with King Tristan.
