Suspense builds in this novel about scientists, physics, time travel, and saving the Earth. It's 1998, and a physicist in Cambridge, England, attempts to send a message backward in time. Earth is falling apart, and a government faction supports the project in hopes of diverting or avoiding the environmental disasters beginning to tear at the edges of civilization. It's 1962, and a physicist in California struggles with his new life on the West Coast, office politics, and the irregularities of data that plague his experiments. The story's perspective toggles between time lines, physicists, and their communities. Timescape presents the subculture and world of scientists in microcosm: the lab, the loves, the grappling for grants, the pressures from university and government, the rewards and trials of relationships with spouses, the pressures of the scientific race, and the thrill of discovery.
