For almost a year Amber and Alex have been left alone by the mysterious "Guardians" who'd taken it upon themselves to protect the creatures of Loch Ness at any cost, even murder. Then, when a government agent goes missing in the Democratic Republic of the Congo while on the track of one of the "Guardians," the President of the United States himself sends for Alex and Amber. Because they've discovered something extraordinary, something impossible, something unearthly...and they want Alex and Amber to go to the Congo and bring it back. But the secret organization known only as "The Guardians" aren't slumbering. While the last time it was the human factor that proved to be the most dangerous, this time, the cryptid they're after is right out of their worst nightmares
