Rendezvous with Rama written by Arthur C. Clarke performed by Hayward Morse on Cassette (Unabridged)

Winner of the 1973 Nebula and BSFA Awards and the 1974 Hugo, Campbell, and Locus Awards. At first, only a few things are known about the celestial object that astronomers dub Rama. It is huge, weighing more than 10 trillion tons. And it is hurtling through the solar system at inconceivable speed. Then a space probe confirms the unthinkable: Rama is no natural object. It is, incredibly, an interstellar spacecraft.

Space explorers and planet-bound scientists alike prepare for mankind's first encounter with alien intelligence. It will kindle their wildest dreams...and fan their darkest fears. For no one knows who the Ramans are or why they have come. And now the moment of rendezvous awaits - just behind a Raman airlock door.
