Jo enlists the help of her friend Andreas. Together they find a hiding place for the rock boy, but it becomes harder and harder to keep their secret. Finally, the only safe place left is The Hypogeum, an ancient underground temple that holds the bones of thousands of people killed in ritual sacrifice...
So what if his father was the only butcher in a village of fishermen, a loner who preferred to spend his evenings carving wood? Is it true what everyone is saying -- that Joshua's father is a 'mountain man', one of the people feared and mistrusted by the villagers?
When Joshua's life takes an surprising turn, he discovers that being different does matter. Maybe it's not enough to be just Joshua?
