The Light of Other Days: A Novel of the Transformation of Humanity

From Arthur C. Clarke, the brilliant mind that brought us "2001: A Space Odyssey," and Stephen Baxter, one of the most cogent SF writers of his generation, comes a novel of a day, not so far in the future, when the barriers of time and distance have suddenly turned to glass.
When a brilliant, driven industrialist harnesses cutting-edge physics to enable people everywhere, at trivial cost, to see one another at all times--around every corner, through every wall--the result is the sudden and complete abolition of human privacy, forever. Then the same technology proves able to look backward in time as well. "The Light of Other Days "is a story that will change your view of what it is to be human.
