Trouble stirs beneath the ice...A breathtaking action adventure from the NEW YORK TIMES bestselling author of MAP OF BONES and THE DOOMSDAY KEY.

Buried deep in the polar ice cap, Ice Station Grendel has been abandoned for more than seventy years. The twisted brainchild of the finest minds of the former Soviet Union, it was designed to be inaccessible and virtually invisible. But an American research vessel has inadvertently pulled too close - and something has been sighted moving inside the allegedly deserted facility, something whose survival defies every natural law...

And now, as scientists, soldiers, intelligence operatives and unsuspecting civilians are drawn into Grendel's lethal vortex, the most extreme measures possible will be undertaken to protect its dark mysteries - because the terrible truths submerged under the ice could end human life on Earth.
