Special Forces officer Mike Turcotte has seen it all. He has been the leader of the government's top secret base at Area 51, attempting to understand how mankind has been influenced for millenia by an alien race called the Airlia. He has battled the aliens and the humans allied with them, from the depths of a South American jungle to the top of the world's tallest mountain. Now, the final battle will commence, and win or lose, the mysteries will be solved.

Throughout the long war, Mike Turcotte has tasted both victory and defeat. For every battle he has won, he has been forced to witness the death of another member of Area 51. No more. The stalemate is over, and Turcotte has the advantage, and with it, the hopes of ridding the world forever of the remnants of the Airlia and the men and women who support them. But the most dangerous animal is a wounded one, and Turcotte knows that his mission is not yet completed. With victory in his grasp, a new threat appears that could destroy the world, and it is a danger that cannot be easily accessed, for the threat originates on Mars. Turcotte will have to decipher the riddle of Stonehenge and the enigma of Nikola Tesla if he hopes to gain a final victory.

But instrumental to his success is the fate of his lover and fellow Area 51 member Lisa Duncan. Her past seems as mysterious as the Pyramids themselves, but she is the key to the one elusive element that will win or lose the war -- she possesses the truth.
