The year is A.D. 922. A refined Arab courtier, representative of the powerful Caliph of Baghdad, encounters a party of Viking warriors who are journeying to the barbaric North. He is appalled by their Viking customs - the wanton sexuality of their pale, angular women, their disregard for cleanliness...their cold-blooded human sacrifices. But it is not until they reach the depths of the Northland that the courtier learns the horrifying and inescapable truth.

Once again Michael Crichton gives us his trademark combination of page-turning suspense, cutting-edge technology, and extraordinary research. State of Fear is a superb blend of edge-of-your-seat suspense and thought provoking commentary on how information is manipulated in the modern world.

The year is 1876. Warring Indian tribes still populate America's western territories, even as lawless gold-rush towns begin to mark the landscape. In much of the country, it is still illegal to espouse evolution. Against this backdrop two monomaniacal paleontologists pillage the Wild West, hunting for dinosaur fossils while surveilling, deceiving, and sabotaging each other in a rivalry that will come to be known as the Bone Wars.

Deep in the African rain forest, near the legendary ruins of the Lost City of Zinj, an expedition of eight American geologists are mysteriously and brutally killed in a matter of minutes.

A classic thriller from #1 New York Times bestselling author Michael Crichton, Sphere is a bravura demonstration of what he does better than anyone: riveting storytelling that combines frighteningly plausible, cutting-edge science and technology with pulse-pounding action and serious chills.
