A dark mystery has been buried beneath the sands of the Sahara for eons. In a basement in New Mexico, four poker buddies find reason to believe that a startling secret is out there, and these four amateur adventurers are about to uncover it.

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. 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 survive the journey back to Earth.
