The second book in the Nina Wilde and Eddie Chase series, 2008

One hundred miles off the southern coast of Portugal was hidden one of the greatest secrets in human history.

For now, it would remain hidden, guarded by another secret of much more recent origin.

Officially, the giant six-legged floating platform was listed as SBX- 2, a sea-based X-band radar station. Nicknamed the Taj Mahal for the huge white radar dome dominating its upper deck, the high-tech U.S. Navy behemoth swept the skies to the east for thousands of miles, its stated purpose to monitor North Africa and the Middle East for ballistic missile launches. In function and application, it was what it claimed to be.

But that was not the real reason for its presence. The truth lay eight hundred feet below.

Fifteen months earlier, the citadel at the heart of the lost civilization of Atlantis-long believed to be nothing more than a legend-had been discovered directly beneath where the SBX was now anchored. Though the only visible structure, the huge Temple of Poseidon, had been destroyed, radar surveys had revealed many more buried beneath the silt covering the seafloor. Since the discovery of Atlantis had ultimately turned out to be part of a conspiracy to exterminate three-quarters of humanity with a biological weapon, the Western governments that stepped in after the plot was foiled decided that not only the circumstances of the ancient city’s discovery, but also the mere fact of its existence should remain a secret. At least, until a more benign story of its finding could be concocted-and any danger of someone repeating the genocidal plan eliminated.
