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. The gripping story of a group of American scientists sent to the ocean floor to investigate an alien ship, only to confront a terrifying discovery that defies imagination, Sphere is Crichton prime—truly masterful fiction from the ingenious mind that brought us Prey, State of Fear, and Jurassic Park.

Sphere was made into a film directed by Barry Levinson, which starred Dustin Hoffman, Sharon Stone, and Samuel L. Jackson.
