Shona is led to believe the unbelievable – that Jimmy is "Benjamin," the half-mermaid half-human mentioned in the prophecies of destruction. But one problem remains: the prophecy foretells of a girl! The strange twins who exactly resemble Jimmy are the only ones who seem to know the full truth about the boy and the nature of his bizarre powers. Although they claim to be protecting him, they appear to have their own agenda. Only time will tell whether they are allies…or enemies in disguise.
