A shape-shifter story about evil, heroines, love and magic. The Houses are five branches of shape-shifters, each with their own unique traits and abilities. They live within their own walls, mostly cut off from the harsh world around them. Every generation a new Head of House takes over in each house to look after and govern their people. Now, for the first time in centuries, all five future Heads of House are female. No-one knows what the future will bring, only that the world is about to change forever.
