Books of the Ancestor

At the Convent of Sweet Mercy, young girls are raised to be killers. In a few the old bloods show, gifting talents rarely seen since the tribes beached their ships on Abeth. Sweet Mercy hones its novices' skills to deadly effect: it takes 10 years to educate a Red Sister in the ways of blade and fist. But even the mistresses of sword and shadow don't truly understand what they have purchased when Nona Grey is brought to their halls as a bloodstained child of eight, falsely accused of murder - guilty of worse.

The second novel in the brilliant new series from the best-selling author of Prince of Thorns. In Mystic Class, Nona Grey begins to learn the secrets of the universe. But so often even the deepest truths just make our choices harder. Before she leaves the Convent of Sweet Mercy, Nona must choose her path and take the red of a Martial Sister, the grey of a Sister of Discretion, the blue of a Mystic Sister or the simple black of a Bride of the Ancestor and a life of prayer and service.

They came against her as a child. Now they face the woman. The ice is advancing, the Corridor narrowing, and the empire is under siege from the Scithrowl in the east and the Durns in the west. Everywhere, the emperor’s armies are in retreat. Nona faces the final challenges that must be overcome if she is to become a full sister in the order of her choice. But it seems unlikely that Nona and her friends will have time to earn a nun’s habit before war is on their doorstep.
