Sphere

In the South Pacific, 1000 feet beneath the surface, a spaceship rests on the ocean floor - a spaceship at least 300 years old. Has it come from an alien culture? From a different universe? From the future?

Four scientists are rushed to the scene: an astrophysicist, a biologist, a mathematician and a psychologist and together they descend into the depths of the sea to investigate.

The riddle seems unsolvable. Then someone or something begins to transmit messages onto their computer screen: messages that grow increasingly hostile and hint at a terrifying power...

SPHERE is Michael Crichton at the top of his form. An astounding combination of action, suspense and science that probes the darkest corners of the mind where man's deadliest enemy lurks. --back cover
