The Will of the Empress, previously titled The Circle Reforged, is a standalone fantasy novel by Tamora Pierce, a continuation of the story of the quartets Circle of Magic and The Circle Opens. Plot summary Empress Berenene The primary plot of the novel is the struggle of Sandrilene fa Toren, a half-Namornese noblewoman, against her cousin, Empress Berenene of Namorn; Sandry had inherited the vast Namornese estate of Landreg from her mother, who had accustomed her to receiving a yearly income from the estate while rarely visiting it. Empress Berenene, who wants to keep the revenue from the estate within Namorn, repeatedly invites Sandry to visit her court in Dancruan while levying increasing taxes from her estate. When Sandry realizes that the Empress has been threatening Namorn's amicable trade with Emelan, she decides to accept the Empress's invitation and use the visit to visit her estate and Namornese family. Sandry's uncle, Duke Vedris of Emelan, asks her childhood companions Daja Kisubo, Trisana Chandler and Briar Moss who have just come back from their travels to accompany her in lieu of a company of guards, a gesture both discourteous and ineffectual. Though their friendship with Sandry and with each other has become strained since their return to Summersea after years of world-traveling, Daja, Tris and Briar agree, and the four travel to Namorn together. While there, they learn of the Western Namornese custom of bride kidnapping, which entails a man kidnapping a prospective bride and holding her captive until she agrees to sign a wedding contract. While the so-called "horse's rump" wedding is usually only used to bypass reluctant families or out of a sense of adventure, some marriages are forced, and the custom remains legal. Empress Berenene has never attempted to illegalize it despite having twice been kidnapped, because she believes her ability to escape both times means that only weak women would allow themselves to be forced into a marriage they don't want. When he hears of this, Briar comments that the Empress's captors are unlikely to have used the same level of violence as a common woman might encounter. Because of their power and renown, Empress Berenene decides that Namorn stands to benefit if she persuades all four mages to remain in her court, in addition to Sandry and the funds from her Namornese estate. She offers Tris a position as a court mage with a large salary
