The Yellowstone supervolcano has begun to erupt, sending North America into chaos and the rest of the world into a panic. People are dangerous and desperate, knowing this will plunge the continent, and the world, into perpetual winter.

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.

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.

Deputy Thomas Rodney is no stranger to tense situations. Having served multiple tours in the worst of environments, facing death had practically become just another day at the office. But nothing could have prepared him for this. In a woodland county in the Pacific Northwest, a sinister presence has awakened. A roadwork crew has disappeared without a trace; a truck is found run off the road; a lakefront property is mysteriously vacant, its roof damaged as though something large descended from high above; and an eerie quiet has overtaken the countryside.

Alex Hunter - in the mission that turned him from a normal man into the weapon known as the Arcadian - and the elite team of soldiers known as the Hotzone All-Forces Warfare Commandos must enter a hostile country to rescue a defected Chechen researcher from the centre of a country at war. But the HAWCs are not the only ones looking for the rogue scientist and the mysterious package he carries with him. A brutal and relentless killer and his death squad are on the trail, too - and they bring a savagery with them that Hunter and his team have never witnessed before in modern warfare.

Planetary geologist Dr. Micah Clarke, his nine-year-old daughter Faye, and his assistant Catalina Abril are abducted at gunpoint and forced to join a megalomaniac’s paramilitary expedition down an Amazon tributary ruled by murderous pirates and cannibal tribes. The goal—recover a meteorite capable of providing clean energy for the world. But prehistoric terrors lurk around every bend in the river. Swarms of six-inch titan ants, mega piranha, and a 70-foot Titanoboa tear a bloody swath through the flotilla.

The world’s food supply grows aggressively, occupying every inch of earth, no matter how inhospitable. World hunger is averted. Humanity flourishes. RC-714 is digested, absorbed…and passed on. The Change affects small fast-breeding mammals first. They multiply with the same aggressive speed as the ExoGen plants, but an insatiable hunger drives them to violence. A war between species breaks out. When RC-714 reaches humanity, along with every other large creature on the planet, civilization implodes.

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.

Lincoln Miller, an ex-Navy SEAL turned NCIS special agent, is sent to Aquarius, the world’s only sub-oceanic research facility, located off the Florida Keys, to investigate reports of ocean dumping. A week into his stay, strange red flakes descend from the surface. Scores of fish are dead and dying, poisoned by the debris that turns to powder in Miller’s fingers and tastes like blood. Miller heads for the surface, ready to fight whoever is polluting on his watch. But he finds nothing. No ships. No polluters.... No oxygen.

Awakened from ancient slumber, something stalks the swirling, grey mists that surround Lawless. A beast with a gnawing hunger that grows stronger by the minute - its only thought, to satisfy its ravenous appetite.
