It was a legendary island, a fantastic island. Atlantis. Or as its prince called it, Athilan.

Roy had traveled through time with his partner, Lora, to find it-and now he was tantalizingly close to its shore.

Time travel allowed Roy's consciousness to enter the mind of the heir to Atlantis' throne, and what he found disturbed him. Strange dreams. Impossibly futuristic inventions and machines. How could such an advanced city exist at this time? The rest of the world was, as Lora witnessed in her travels, a dark, barbaric land still thawing from the ice age.

Roy had been preparing for the odd isolation of time travel, but nothing had prepared him for his final arrival on Atlantis-a shimmering city far beyond his imagination! Roy knew this island's fate. According to legend, it would vanish into the sea. Roy also knew he had a limited amount of time to decipher the strange message in the Prince's mind-visions of cataclysmic events, mysterious rites to a faraway star.

If Roy was in an Atlantis unlike anything the researchers had predicted, then what were its secrets? And when would it be destroyed?
