Treachery, greed, and a gargantuan sea monster threaten the inhabitants of a high-tech, deep-water research station in this thrilling undersea science fiction adventure A three-time Hugo Award winner and modern master of hard science fiction now departs from outer space for a vast, unexplored realm that is equally perilous and mysterious. Allen Steele's Oceanspace is a heart-racing near-future adventure of danger and discovery unfolding in the dark, cold, and merciless depths of the ocean.   The undersea research facility Tethys is a technological wonder, self-sufficient and seemingly impervious to natural danger. Located off the coast of Florida deep beneath the surface of the water, the station supports a robotic mining operation on the ocean floor and facilitates the ongoing scientific exploration of Earth's last frontier. But while on a routine assignment with his colleague Peter Lipscomb, submersible pilot Joe Niedzwiecki comes face to face with something incredible and alive, and only luck--and Peter's quick actions--can save them.   Peter's wife, a marine biologist named Judith, is determined to uncover the secrets of the mysterious leviathan that destroyed Joe's sub and nearly killed him. But the strange creature prowling the dark waters is only one of the dangers confronting Tethys.
