This is the way the world ends. Not with a bang but a scream. In the remote mountains of Northern Alaska, Dr. Riley Middleton and her team of archeologists discover a burial site containing mummified remains dating to the last ice age.

But there’s something even more terrifying inside...something ancient...something unspeakably evil.

When the body of Hunter Gearhardt washes up on the banks of a seasonal river outside of Pomacochas, Peru, with only samples of vegetation, a handful of feathers, two black- and gray-streaked rocks, and a golden headdress of indeterminate origin in his possession, his grieving father launches an expedition to determine how his son died. The party uses these clues to divine Hunter’s route into the jungle, where they find a surviving offshoot of a primitive tribe, long thought to be extinct, and something far more sinister, something that’s been able to avoid discovery for eons for one simple reason: No one leaves the rainforest alive.

Something lurks in the darkness, though. A creature has evolved into a predator unlike any the world has ever known, and it's up to the scientists to make sure that it never reaches the surface.

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.
