A story of loyalties tested, secrets exposed, and one boy’s search for identity amid the tangled political intrigue and deception of the Dark Ages.

A young thief known as "the Ghost" roams seventh-century Constantinople, tangling in political feuds and petty theft, using his eerie gifts of persuasion and stealth. With his father away at war and his mother devastated by his little sister’s death, Cai would rather be anywhere than at home. But when a rival ambushes and sells Cai as a slave, he begins to regret his choices. Aboard the slavers’ ship, Cai travels far from the warmth of Constantinople into his parents’ homeland — the forbidding land of Britain, where war is brewing between tribes. Bought by a clan head, Cai finds a new life as a tribal member, and using his uncanny talents, is put to work as a spy. The secrets he discovers, however, kindle doubt and disloyalty in his heart. Adrift in a society he still feels apart from, Cai seeks truth and revenge, throwing his life to the wind with startling results.
