THE WILL OF THE EMPRESS (Tamora Pierce)

Synopsis of "The Will of the Empress", first book of "The Circle Reforged" by Tamora Pierce: On visit to Namorn to visit her vast landholdings and her devious cousin, Empress Berenene, eighteen-year-old Sandry must rely on her childhood friends and fellow mages, Daja, Tris, and Briar, despite the distance that has grown between them.

For many years, Sandry's cousin, the Empress of Namorn, has pressed her to visit. But Sandry prefers to stay with her own family in Emelan. Now, as is her right, the Empress has insisted. Sandry will not travel with a group of warriors -- that would only insult the Empress. She will travel with her friends from Winding Circle: Daja, Briar, and Tris. But the four young mages haven't been together in some time, and their friendship isn't what it used to be. Since they left Winding Circle, each has seen magic manipulated in ways -- both good and bad -- that they could not have imagined

Daja, Briar, Tris, and Sandry have grown up and grown apart since their days together at Winding Circle, and Sandry's especially disappointed with the change. When Sandry's uncle requests that her three old friends accompany her on a visit to Sandry's vast lands within the Empire of Namorn, the young mages discover that they've landed in a trap. Namorn's iron-willed Empress has plans for Sandry and her companions, and she has wily and powerful mages to help her. But so, of course, does Sandry--if only she can get them to work together..
