In a twisting, fast-moving adventure, ex-Navy Seal Nolan Kilkenny finds himself on a dangerous mission where he must recover a priceless artifact. Deep in the frozen wasteland of Antarctica, a remote NASA research lab rests atop a two-mile thick glacier, covering a vast underground water reservoir. But the true discovery isn't the lake buried in ice - it's what has been found within its boundaries. Something amazing, something alive, and it may hold the answers to existence itself. A bestseller in the US, author Tom Grace is one of the masters of intrigue.
