    With sweating hands, Alison Shaw stared nervously into the giant seawater tank. One year ago, she and her team of marine biologists had stunned the world with an incredible breakthrough. Now they were about to do it again. And this time, they were ready. But an ocean away, something strange was unfolding. Along a lonely coast in South America, an experimental Russian submarine - long thought to have been dismantled - has suddenly resurfaced. And the US Navy has taken notice, sending John Clay and Steve Caesare to investigate.
