On a lonely stretch of shore, not far from Buenos Aires, Dr. Salvator lives in seclusion behind a high wall, whose steel-plated gates only open to let in his Indian patients. The Indians revere him as a God but Zurita has a hunch that the God on land and the devil in the sea have something in common. Enlisting the help of two wily Araucanian brothers he sets out to probe the mystery.

As action shifts from the bottom of the sea to the Spaniard's schooner The Jellyfish and back again, with interludes in sun-drenched Buenos Aires and countryside, the mystery of Ichthyander the sea-devil is unfolded before the reader in a narrative as gripping as it informative.

Over the past century humankind has managed to do the impossible and rein in famine, plague, and war. This may seem hard to accept, but, as Harari explains in his trademark style—thorough, yet riveting—famine, plague and war have been transformed from incomprehensible and uncontrollable forces of nature into manageable challenges. For the first time ever, more people die from eating too much than from eating too little; more people die from old age than from infectious diseases; and more people commit suicide than are killed by soldiers, terrorists and criminals put together. The average American is a thousand times more likely to die from binging at McDonalds than from being blown up by Al Qaeda.

What then will replace famine, plague, and war at the top of the human agenda? As the self-made gods of planet earth, what destinies will we set ourselves, and which quests will we undertake? Homo Deus��explores the projects, dreams and nightmares that will shape the twenty-first century—from overcoming death to creating artificial life. It asks the fundamental questions: Where do we go from here? And how will we protect this fragile world from our own destructive powers? This is the next stage of evolution. This is��Homo Deus.

With the same insight and clarity that made Sapiens an international hit and a New York Times bestseller, Harari maps out our future.
