The Curse of Chalion
Lois McMaster Bujold
 Lupe dy Cazaril, a castillar (a knight or minor baron), returns home to the Royacy (Kingdom) of Chalion a broken man, though he is only in his mid-thirties. "Caz", as he is known to his friends, had defended a castle during a long siege, only to be ordered to surrender it. Afterward, a jealous enemy had seen to it that he was not ransomed (as were the rest of his men), but sold into slavery, spending 19 months as a galley slave before finally escaping. His old noble patroness finds a use for him as a tutor for her granddaughter, the Royesse (Princess) Iselle, half-sister to the king, and her companion, Lady Betriz. Despite his ardent desire to live a safely low-profile, peaceful life, Caz finds himself drawn into a strange journey of dangers both spiritual and temporal as he seeks to dispel the debilitating curse that hangs over the royal family of Chalion.
