Mankind is no longer the dominant species. When Harrison Kent suggests an outing to a remote campsite in Colorado, his friends are all eager for a few days of fun and adventure. What awaits them, though, is far more than they ever bargained for. They learn that Sasquatch is real, but these are not the shy creatures of legend. A madness has claimed them, erasing their once peaceful nature and leaving in its wake a rampaging horde of monsters that's about to descend upon the unsuspecting residents of a remote town.

On a desolate beach in far northern Scotland, the winter storms have been washing up all manner of things since time began. But buried in the centre of one smaller iceberg is a shard of ancient Viking pottery telling a partial tale of a hidden mysterious island beyond the ice and mist, that was home to a great treasure and even greater horrors. Thawing in the same block of ice was a rotting flap of skin that refused to be identified but had similar skin patterns to a creature not seen for 100 million years.

At the edge of chaos, one geek stands tall. Five years ago, dateless dork Bill Ryder somehow saved the world, banishing magic and monsters to the shadows. He thought it was over, that he was finished with that life. Too bad for him, shit’s about to get surreal again. Now the impossible has happened. His goddaughter is conjuring fireballs from thin air and two vampires have shown up at his doorstep looking to kick his ass.

A series of bizarre occurrences suddenly plague the island of Cielo Nublado. A dead whale washes ashore riddled with enormous bite marks. A fishing charter is reported missing, jet skiers vanish, and a yacht is found mysteriously ravaged after some kind of enormous impact. Chief of Police Nico Medrano tries to investigate the matter. His search for answers puts him on a collision course with an 80-foot predator, long thought extinct. Violent and merciless, it has risen to the surface, and seeks to wreak havoc on the small island community.

Mark Hawkins, former park ranger and expert tracker, is out of his element, working onboard the Magellan, a research vessel studying the Great Pacific Garbage Patch. But his work is interrupted when, surrounded by 30 miles of refuse, the ship and its high-tech systems are plagued by a series of strange malfunctions and the crew is battered by a raging storm. When the storm fades and the sun rises, the beaten crew awakens to find themselves anchored in the protective cove of a tropical island...and no one knows how they got there.
