The South of France, 1790—Mireille de Remy and her cousin Valentine are young novices at the fortresslike Montglane Abbey. With France aflame in revolution, the two girls burn to rebel against constricted convent life—and their means of escape is at hand. Buried deep within the abbey are pieces of the Montglane Chess Service, once owned by Charlemagne. Whoever reassembles the pieces can play a game of unlimited power. But to keep the Game a secret from those who would abuse it, the two young women must scatter the pieces throughout the world. . . .
