Director Eric Red's third novel is a throwback to 80's deep sea monster movies, along the lines of LEVIATHAN and DEEPSTAR SIX. In the 1800's an asteroid crashes into a Spanish warship, sinking it down to bottom of the Mariana Trench, the deepest spot on earth. In the present, two brothers, Roy and Sebastian Enright, have invented an experimental sub--and deep sea diving suit, to recover the millions of dollars worth of gold. Roy is more the administrator and Sebastian the daredevil. So it's he who goes own in the sub, along with a Russian pilot, Polidori, and Jane Clark, who he's also screwing. But once they get down to the bottom and locate the ship, they see a strange glowing. It's the asteroid--and it has brought alien life with it. It has taken over the bottom sea lifeforms--crabs--and it wants to go to the surface, via these humans. Polidori is taken over at first--and Sebastian and Clark have to survive the encounter. Meanwhile, a rival treasure hunter has followed the ship that's on the surface and plan to steal the treasure--and probably kill everyone as well. It all culminates with a confrontation between these bad guys and the monster, which has mutated a great white shark This is an entertaining creature tale. It's as if James Rollins or Matthew Reilly wrote a Roger Corman movie.
