Beyond imagination. A menacing stone sculpture in the middle of the Sahara. A research group lost in a labyrinth of caves. And a woman who is the only one who can interpret the cryptic signs ? Amid ancient rock paintings deep in the heart of the Sahara, Hannah Peters, an experienced archaeologist, makes a startling discovery. A Medusa sculpture decorated with maps and symbols; a harbinger of a lost cult of fabulous beauty and sinister power. When a team from the National Geographic Society joins Hannah on her treasure hunt, she is overcome by a deep sense of foreboding. And the nightmare begins. Human senses are incapable of comprehending what the stone eye of the Medusa is capable of. It is not meant for the living ?
