In the most exciting SF collaboration ever, Arthur C. Clarke and his universally acknowledged heir Stephen Baxter pool talent, fantastic ideas, unprecedented cosmic insights as well as page-turning plotting skills and breathlessly good writing to produce the most awesome novel of the future since 3001. 'Space is what keeps everything from being in the same place. Right?' With these words Hiram Patterson, head of the giant media corporation OurWorld, launches the greatest communications revolution in history. With OurWorld's development of wormhole technology, any point in space can be connected to any other, faster than the speed of light. Realtime television coverage is here: earthquakes and wars, murders and disasters can be watched, exactly as they occur, anywhere on the planet. Then WormCams are made to work across time as well as space. Humanity encounters itself in the light of other days. We witness the life of Jesus, go to the premiere of Hamlet, solve the enigmas that have baffled generations. Blood spilled centuries ago flows vividly once more - and no personal treachery or shame can be concealed. But when the world and everything in it becomes as transparent as glass and there are no more secrets, people find new ways to gain vengeance and commit crime, and Hiram Patterson finds new ways to keep his Machiavellian schemes secret.
