All is going well—much horseback riding on the island's trails, a cute local boy who rides, beautiful moors, beaches for swimming. . . . Until people start mysteriously getting hurt, and someone seems to be stalking Tia and her friends. The mystery is unraveled by Tia after much courageous riding, leading to a dramatic climax.
