Our view
“Sphere” opens as a novel of ideas, with a crew deep under the sea reasoning through what contact with an alien intelligence might mean. The science feels plausible; later the book shifts towards psychological suspense and a rapid series of twists, which some readers find gripping and others one turn too many. It is an easy, fast read for anyone who likes thrillers built on ideas.
