The Stonehenge Gate
by Jack Williamson

Description:
A dark mystery has been buried beneath the sands of the Sahara desert since the beginning of time. In a basement in New Mexico, four poker buddies find reason to believe that a startling secret is out there. . .

These four amateur adventurers are about to uncover the key that could unlock the vast reaches of the universe.

A sudden burst of curiosity propels mild-mannered English professor Will and his three friends to the Sahara to excavate a site where radar has evidently detected trilithic stones hidden beneath the sand. There they stumble upon an ancient artifact that will change their lives, and the world, forever...a gateway between planets, linking Earth to distant worlds where they will discover wonders and terrors beyond imagining.

Jack Williamson, the dean of science fiction writers, weaves an exciting tale that takes the friends to the far corners of the universe. One leads an oppressed people to freedom. Another uncovers clues that could identify a long-dormant civilization of immortal beings. Now each traveler must play a crucial role in unraveling an ancient mystery, the solution to which may reveal the true origins of the human race.

If they can just survive their journeys back to Earth . . .
