The evil sorcerer Markko has sworn to capture the last of Prince Llesho's brothers. If Markko succeeds, Llesho will not be able to save Thebin, or reopen the Gates of Heaven. As murder and dark magic threaten Llesho's alliances, he realizes his only chance lies in finding his brothers first. So begins a desperate hunt that will lead the prince from the slave market to a sea voyage fraught with perils, and an incredible discovery about the sorcerer who seems bent on his destruction.
