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. None of them notice the warning carved into the entrance or realize that the tomb had been deliberately sealed from the outside until they’ve already released a virus that turns ordinary people into murderous monsters. But there’s something even more terrifying inside...something ancient...something unspeakably evil.

The fossilized remains of a previously unclassified hominin species are discovered in the Altai Mountains, prompting teams of scientists from around the globe to converge upon this isolated region of Siberia in search of further evidence to corroborate the revolutionary theory that a third proto-human ancestor coexisted with Neanderthals and primitive Homo sapiens. What awaits them is anything but extinct.

A young girl vanishes in broad daylight on her tenth birthday. Her father, FBI Special Agent Phil Preston of the Child Abduction Rapid Deployment Team, devotes his life to finding her and discovers a pattern in a recent string of abductions. Dr. Les Grant leads a group of graduate students into the Wyoming wilderness in search of an unidentified Native American medicine wheel photographed by an anonymous hiker. Instead, they stumble upon a macabre tableau of suffering.

When the Air National Guard receives an emergency call for help from a remote Arctic research station in Greenland, Senior Master Sergeant Dan Cameron is chosen to lead the rescue mission. In an attempt to combat climate change, the scientists have genetically engineered an aquatic biofilm capable of generating oxygen and lowering the temperature of the underlying seawater, producing environmental conditions that awaken an organism that has lain dormant beneath the ocean floor for millions of years.

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.
