A distressingly suspenseful follow up to Silver Child, this book hunkers down in the terrifying new world that is unfolding in Coldharbour and shows you more of what is happening to the children there so that they can protect the world. You learn what is making the terrifying roar and it is even more frightening than the disembodied roar alone. This book neatly faces issues of sacrifice and self-awareness and really makes you think.
