Collected here are four books in the Space Odyssey series. 

AS1 - On the Moon, an enigma is uncovered.

So great are the implications of this discovery that for the first time men are sent out deep into our solar system.

But long before their destination is reached, things begin to go horribly, inexplicably wrong...

One of the greatest-selling science fiction novels of our time, this classic book will grip you to the very end.

AS2 - When 2001: A Space Odyssey first shocked, amazed, and delighted millions in the late 1960s, the novel was quickly recognized as a classic. Since then, its fame has grown steadily among the multitudes who have read the novel or seen the film based on it. Yet, along with almost universal acclaim, a host of questions has grown more insistent through the years:

Who or what transformed Dave Bowman into the Star-Child? What purpose lay behind the transformation? What would become of the Star-Child?

What alien purpose lay behind the monoliths on the Moon and out in space?

What could drive HAL, a stable, intelligent computer, to kill the crew? Was HAL really insane? What happened to HAL and the spaceship Discovery after Dave Bowman disappeared?

Would there be a sequel?

Now all those questions and many more have been answered. In this stunning sequel to his international bestseller, Clarke has written what will truly be one of the great books of the '80s. Cosmic in sweep, eloquent in its depiction of Man's place in the Universe, and filled with the romance of space, this novel is a monumental achievement.

AS3 - Heywood Floyd, survivor of two previous encounters with the mysterious monloiths, must again confront Dave Bowman, HAL, and an alien race that has decided that Mankind is to play a part in the evolution of the galaxy whether it wishes to or not

AS4 - The mysteries of the monoliths are revealed in this inspired conclusion to the Hugo Award–winning Space Odyssey series—“there are marvels aplenty” (The New York Times).

On an ill-fated mission to Jupiter in 2001, the mutinous supercomputer HAL sent crewmembers David Bowman and Frank Poole into the frozen void of space. Bowman’s strange transformation into a Star Child is traced through the novels 2010 and 2061. But now, a thousand years after his death, Frank Poole is brought back to life—and thrust into a world far more technically advanced than the one he left behind.

Poole discovers a world of human minds interfacing directly with computers, genetically engineered dinosaur servants, and massive space elevators built around the equator. He also discovers an impending threat to humanity lurking within the enigmatic monoliths. To fight it, Poole must join forces with Bowman and HAL, now fused into one corporeal consciousness—and the only being with the power to thwart the monoliths’ mysterious creators.
