THE BATTLE TO SAVE HUMANITY HAS BEGUN. Off the coast of Antarctica, a research vessel discovers a mysterious structure buried deep within an iceberg. Entombed for thousands of years, it can't possibly be man-made. But a secretive and ruthless cabal think they know what it is... and what it means. The Immari have spent millennia preparing for the return of humanity's ancient enemy. Faced with an extinction-level threat, they believe mankind's only chance of survival will mean sacrificing 99.9% of the planet's population. It's a price the Immari are prepared to pay. Geneticist Kate Warner and intelligence agent David Vale may have a chance to avert the looming catastrophe, but only if they can decode the secrets of the Atlantis Gene and unlock the truth about humanity's origins.
