Beyond The Ice Limit - Douglas Preston, Lincoln Child

60° SOUTH: NOTHING BUT SEA, ICE AND UNFETTERED STORMS. BUT TWO MILES DOWN, SOMETHING IS STIRRING. Five years ago, Eli Glinn led a mission to recover a 25,000-ton meteorite - the largest ever discovered - from a remote island off the coast of South America. It ended in disaster when their ship foundered and broke apart in a vicious storm. But now, two miles down in dark Antarctic waters, something is growing. A vast, grotesque structure is simultaneously reaching up towards the waves and burrowing deep into the sea floor. Eli Glinn's worst fear has been realised. He has no choice but to return to the Southern Ocean and attempt to annihilate an entity that threatens the existence of the planet. But, as he will discover, the entity has no intention of going quietly.
