His father is a traitor, but he is destined to save the Roman Empire. As soon as Marcus Valerius arrives in Britain, he must fear for his life, as Emperor Commodus has sentenced him to death. This leaves Marcus no choice but to serve under a false name in a legion at Hadrian's Wall, until justice eventually finds him. Then, a rebel army ready for anything storms the wall, and his chance has come. As a centurion, Marcus must prove that he can lead his men to victory in the bloody battle.
