The Atlantis World: The Origin Mystery, Book 3 by A. G. Riddle

70,000 years ago, the human race almost went extinct. We survived, but no one knows how. Now the next stage of human evolution is beginning. Will we survive this time? Geneticist Kate Warner and counter-terrorism agent David Vale have prevented a fierce plague from wiping out humanity - but the struggle to survive is far from over. The Atlantis World stretches deep into space and time, harbouring an enemy greater than anyone had imagined. Now Kate and David must race through galaxies, past space stations, and into the past of a mysterious culture whose secrets could save humanity in its darkest hour. This is the blockbusting final instalment in the Origin Mysteries.
