Maurey has always been persecuted for the colour of his skin and eyes. He has never known more about his parents than that his mother died the day he was born. When the king's chancellor discovers that Maurey possesses a ring belonging to the missing queen and another that may be the key to finding the hidden kingdom of the inhuman warlocks of Talverdin, he is imprisoned, revealed as a Nightwalker, and sentenced to execution in philosopher's fire. Rescued by a young baroness with her own reasons for fearing the chancellor, Maurey sets out on a dangerous journey to the land of his father's people. If he and Annot are to survive and prevent the destruction of the last refuge of the Nightwalkers, Maurey will have to call on human and inhuman skills he never knew he possessed, and win the trust of both sides of his family.
