The Light of Other Days tells the tale of what happens when a brilliant, driven industrialist harnesses the cutting edge of quantum physics to enable people everywhere, at trivial cost, to see one another at all times: around every corner, through every wall, into everyone's most private, hidden, and even intimate moments. It amounts to the sudden and complete abolition of human privacy - forever. Then, as society reels, the same technology proves able to look backwards in time as well. Nothing can prepare us for what this means. It is a fundamental change in the terms of the human condition.
