Clarke, Arthur Charles

The body of Frank Poole, murdered by mad computer HAL a thousand years earlier, is found and revived to a world of peace and plenty, but in his attempts to understand the entity composed of his former deputy Dave Bowman and a copy of the now-sane HAL, Frank learns that Earth is slated for destruction.

Accompanied by a navigator, three deep-freeze hibernauts, and the computer that guides him, David Bowman sets out in the spaceship Discovery to investigate a planet that may be inhabited by alien creatures.
