Book 2. of House of Control Three years have passed since Harry accepted his role as a Master of The House, solidifying his control and expanding his influence over both magic and the lives of those under its roof. As he refines his powers and enforces The House's strict hierarchy, unexpected figures from his past-Neville, Ginny, Draco, and Marcus Flint-are drawn into The House, each facing their own transformation. While Harry teaches Neville the art of wielding magic without a wand, he witnesses old friends become unrecognizable, each adapting to the rigorous demands of servitude, discipline, and loyalty that define life within The House. But as tensions rise and loyalties are tested, questions about The House's true motives and the price of obedience linger, drawing Harry and his allies into a complex web where each choice deepens their bond to the shadows that now define them.
