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.

They discover the sub has been quietly studying a group of soldiers making mysterious trips into the jungle under the cover of darkness. The group has discovered something...something big.

And what Clay and Caesare uncover next is the last thing anyone expects. The discovery of the century has been made...and someone is ready to fight for it.
