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.

They mustn't harm a human being, they must obey human orders, and they must protect their own existence...but only so long as that doesn't violate rules one and two. With these Three Laws of Robotics, humanity embarked on a bold new era of evolution that would open up enormous possibilities, and unforeseen risks.

The Empire stands at the brink of total collapse. But they have saved their most heinous plan for last.

Former naval doctor Peter Crane is summoned to a remote oil platform in the North Atlantic to help diagnose a bizarre medical condition. But when he arrives, Crane learns that the real trouble lies far below on "Deep Storm", a stunningly advanced science-research facility built two miles beneath the surface on the ocean floor. The top-secret structure has been designed for one purpose: to excavate a recently discovered undersea site that may hold the answers to an ancient mystery.

They hunt us. They bomb our worlds for target practice. A star cluster in the constellation of Orion rotates once every 1,000 years. Those who rule there have an ancient tradition: When each cycle ends, they train their fleets by spilling the blood of lesser beings. The enemy fleets are coming again. In response, the Rebel Worlds gather their starships to face the terrifying threat, and this time humanity is asked to stand with them. The last time they considered Earth, Vikings in longboats were raiding English coastlines. Today, we're less primitive. Today, we're a target.

Our outdated navy investigates, both curious and fearful. What they learn from the massive vessel shocks the planet.

As powerful dictators come and go over the course of history, the cadre of dedicated librarians is sworn to obey the lawful government - and use their wits to protect the treasure trove of knowledge they have collected over the millennia.

Leo Graf was just your average highly efficient engineer: mind your own business, fix what's wrong, and move on to the next job. But all that changed on his assignment to the Cay Habitat, where a group of humanoids had been secretly, commercially bioengineered for working in free fall. Could he just stand there and allow the exploitation of hundreds of helpless children merely to enhance the bottom line of a heartless mega-corporation?

He is the last to wake. The label on his sleeper pad identifies him as an admiral of the Evagardian Empire - a surprise as much to him as to the three recent recruits now under his command. He wears no uniform, and he is ignorant of military protocol, but the ship's records confirm he is their superior officer. Whether he is an Evagardian admiral or a spy will be of little consequence if the crew members all end up dead.

When Dal Timgar, of all his medical class, was denied assignment to a general practice patrol ship going out from Hospital Earth to serve the medical needs of the Galactic Confederation, it seemed to him that his eight years of study in the great medical center of the galaxy had ended in failure.

Moth was a beautiful planet, the only one with wings - two great golden clouds suspended in space around it. Here was a wide-open world for any venture a man might scheme. The planet attracted unwary travelers, hardened space-sailors, and merchant buccaneers - a teeming, constantly shifting horde that provided a comfortable income for certain quick-witted fellows like Flinx and his pet flying snake Pip.

An impossibly vast and ancient artificial structure lies below, hidden from the universe under a façade of cratered stone. SCARAB arrived on Tantalus 13 two years ago. An artificially intelligent, self-constructing factory, it was supposed to aid the crew in their mission, to meet their every need.

On June 30, 1908, an object fell from the sky, releasing more energy than a thousand Hiroshima bombs. A Siberian forest was flattened, but the strike left no significant crater. The anomaly came to be known as the Tunguska Event, and scientists have never agreed whether it was the largest meteor strike in recorded history - or something else. Alien artifacts have been uncovered since the 1908 event, and a new star drive is discovered.
