Semi, Miranda, and Arnie are part of a group of 50 British Young Conservationists on their way to a wildlife conservation station deep in the rain forests of Ecuador. After a terrifying mid-air disaster and subsequent crash, these three are the sole survivors, stranded together on a deserted tropical island. Or so they think. Semi, Miranda, and Arnie stumble into the hands of Dr. Franklin, a mad scientist who’s been waiting for them, eager to use them as specimens for his experiments in genetic engineering.

Life on Perseus's island of Serifos hangs in a precarious state of balance - the legacy of war - but his own routines are relaxed and calm. However, a beautiful stranger arrives and shatters the peace for everyone. Perseus is smitten, but others are suspicious, for Andromeda has a unique and potentially powerful gift. But she also has a harsh destiny to fulfil. She must die to save her people, and a stunning, word-changing discovery will die with her - unless Perseus abandons all his beliefs to confront the horror of the Medusa quest. In a mesmerising novel which combines Ann Halam's own skilful blend of magic realism with the rich otherwordly power of a favourite Greek myth, this is a story of hope and survival, and the sheer determination of two young people against all the odds.

What's it like to see your friend transformed into a raven before your very eyes, and to know it's your turn next? How does it feel to morph into a manta ray or slide into the body of a snake? This is what happens to Miranda, Semi and Arnie, three friends who are the sole survivors of a plane crash. They find themselves on a tropical island of azure waters and white sands. But beyond the palm-fringed beaches lies the hospital run by the sinister Dr Franklin, and the three teenagers are about to become his next patients. Perfect candidates for his experiments in genetic engineering. . . A horrifying, fascinating story that is Ann Halam's most unusual and challenging novel so far.
