But a curse hangs over the entire blighted House of Chalion, and only with the most forbidden magic can Cazaril hope to protect his royal charge. \n \nA man broken in body and spirit, Cazaril returns to the noble household he once served as page and is named secretary-tutor to the beautiful, strong-willed sister of the impetuous boy who is next in line to rule.
