Called to the Deep
Norman, a psychologist, is one of the specialists selected by the US Navy for what he is told is an exploration mission, the kind of situation his old report on handling an air crash was meant for. Physicists, mathematicians, biologists and experts in every field gather information on an apparently ordinary event. Cut off from telephones and with little information, they travel for hours, sleeping in snatches.
The Sphere
About 300 metres down, they find the sphere. Once they enter it, they discover that their thoughts and deepest fears take real form as creatures: snakes, giant squid, jellyfish and more. Realising that their own thoughts can come to life, they grasp the scale of the responsibility this power carries.
Where Did It Come From?
Is the sphere human? The work of an advanced civilisation? Of alien origin? Was it really designed to travel between the stars? Communication with something so foreign seems almost impossible; only the universal language of mathematics offers a way forward. The experts discard theories as the story advances, using science and deduction to explain how the craft and the sphere came to meet at that point in the ocean. Along the way Crichton brings in black holes, space travel, probability and statistics, a real work of popular science that sparks the reader’s curiosity and imagination.
The Team
Norman Johnson, the narrator’s point of view, is joined by Harry Adams, a brilliant and sardonic mathematician, Beth Halpern, a zoologist, and Ted Fielding, an astrophysicist eager to make history, under the command of the Navy’s Captain Barnes. Living in a cramped habitat on the sea floor, cut off from the surface by a storm, the scientists turn on each other as the danger grows. Crichton makes the most of the claustrophobic setting: the darkness outside, the pressure and the knowledge that there is no quick way back up.
A Mind Game
As the story unfolds, the danger turns inward. The sphere’s power means that the greatest threat comes not from outside but from the scientists’ own unconscious fears and desires, and Norman, the psychologist, must try to understand what is happening in the minds of his colleagues, and in his own. That gives the novel a psychological depth unusual in thrillers, and a final question worth thinking about: what would we do with a power we are not mature enough to handle?
Book and Film
Sphere was filmed in 1998 by Barry Levinson, with Dustin Hoffman, Sharon Stone and Samuel L. Jackson. The film follows the novel’s plot but was coolly received; readers generally agree that the book’s slow-building tension and ideas work far better on the page.
Who Will Enjoy It
Fans of underwater adventure, first-contact stories and psychological suspense, and anyone who enjoyed the film and wants the fuller version.
Highly recommended.
Why Read It
Aware of the harm the sphere’s power could do in the wrong hands, the survivors make a striking final choice. As the reviewer puts it, human ingenuity and hope can be stronger than reality itself, and developing the imagination is essential for solving real problems; that is why books like this one, which mix science, mathematics and even biology, are worth reading.
