Book excerpt: Rocco Makepeace is about to make a very unexpected trip. He will meet people that seem as primitive as any he as read about in history books; people who live in caves, who hunt with bows and arrows, who believe in magic and superstition. Some of those people will become very, very special to him. And because of that, Rocco will have a hard time going home. But then Rocco begins to realise that something is wrong-deadly wrong! There is a secret that may mean the end of him and the end of the home he longs to return to.
