Told in two voices, sixteen-year-old Comtesse Emilie, whose yearning to be a physician is below her station, switches places with Annette, who needs training to develop her magic, as their homeland is threatened by war. Emilie des Marais is desperate to escape her noble roots to serve her country as a physician-- but society dictates a noble lady cannot perform such gruesome work. Annette Boucher, from humble beginnings, is desperate to be trained in magic. Emilie and Annette swap lives: Annette attends finishing school as a noble lady to be trained in the ways of divination, while Emilie enrolls to be a physician's assistant, using her natural magical talent to save lives. But when their nation instigates a frivolous war, the two must work together to help the rebellion end a war that is based on lies. -- adapted from jacket
