Publisher's Synopsis
Sci-fi horror about the crew of an oil rig who discover an underground ocean where a terrifying predator awaits. Out in the North Atlantic Ocean near Greenland, the crew of the world's biggest drilling platform, the Colossus, find themselves going deeper than ever before. Despite concern from geologists that they could cause a major disturbance to the seabed, the drillers continue until they find a second 'mirror' ocean. Little do they know, however, that this is the home of the Carcharadon Megalodon: an eleven-ton, 60-foot shark intent on dismembering anything which crosses its territory...
