Now rogue and in league with the Queen's enemies, they must enact the "Albion Initiative": a desperate plan to break Prince Edward out of Bedlam and install him on the throne in the Queen's stead. But with the Queen's executioner and his army on their trail, as well as a possible traitor in their midst, can they do enough to stop the malign tyrant from destroying everything they once swore to protect?
