Crafted 3500 years ago, the first Bible concealed a dark secret – a missing page, torn from its sacred binding. Rumours claimed it wasn't penned by a saint or prophet, but by the Devil himself, revealing the gateway to Hell. In June 2020, a mysterious Middle Eastern earthquake unveiled this long-hidden page, unleashing global terrors: parasitic plagues, grotesque deformities and monstrous entities rising from the ocean's abyss – creatures never meant for daylight.

The first mission to Europa – Jupiter's enigmatic moon – has landed, and humanity’s darkest fears are about to awaken. For years, mankind has speculated that this frozen world harbours a hidden ocean twice the size of all Earth’s oceans combined – an ocean potentially teeming with life. Driven by this tantalising mystery, they venture forth to unlock its secrets. But what they discover in the abyssal depths is far beyond anything they could have imagined.

Down there, beyond the deepest caves, below the crust and the mantle, there is another world. An old woman locked away in a Russian asylum has a secret - knowledge of a 500-year-old manuscript written by a long-dead alchemist that will show a passage to the mythical centre of the Earth. She knows it’s real because 50 years ago, she and a team travelled there. And only she made it back. Today, caving specialist Mike Monroe leads a crew into the world’s deepest cave in the former Soviet Union.

Mike Monroe and Jane Baxter barely survived their terrifying journey to the centre of the Earth. But a burning curiosity still tormented them about the origins of the pale creatures in the stygian darkness of the caves, and why were their dreams also haunted by something huge and monstrous that seemed as old as time itself? Now, news of a Russian military expedition has forced their hands and also meant they must go back to a place they swore they’d never return. But this time they’re going with a team of highly skilled mercenaries and scientists to help them track the Russians.

A journey into the deepest, darkest jungles of the Venezuelan Amazon...and a primeval place and time that mankind was never meant to exist in. Ben Cartwright, former soldier, home to mourn the loss of his father, stumbles upon cryptic letters from the past between author Arthur Conan Doyle and his great-great-grandfather who vanished while exploring the Amazon jungle in 1908. Amazingly, these letters lead Ben to believe that his ancestor’s expedition was the basis for Doyle’s fantastical tale of a lost world inhabited by long-extinct creatures.

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.

Sheriff Colton Graves prefers the quiet life in Raven's Rest, Alaska, a remote town accessible only by tunnel and home to a hardy mix of locals and secrets buried in the ice. But when a camel wanders down Main Street—its head grotesquely sprouting a dozen eyes—Colton knows his quiet days are over. The bizarre incident leads him to NovaGen, a nearby research facility constructed inside a Cold War bunker, buried in the mountains above town. There, a trail of blood and eerie silence hints at something far more sinister than an escaped animal experiment.

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.

100,000 years ago the object hit the lake at the deepest point, quickly sinking into its mile-deep Stygian darkness. The sheets of ice closed, time moved on and the land forgot. But over the centuries, legends grew of people vanishing, of strange, deformed animals and of an unexplained luminescence down in the lake depths. When Marcus Stenson won the lucrative contract to create a sturgeon fish farm on the site of disused paper mill on the shore of Lake Baikal, he thought he had won the lottery and refused to listen to the chilling folktales....

Loch Ness holds secrets, ancient and deadly. Does a monster inhabit its depths, or is it just myth? Why, after thousands of reported sightings and dozens of expeditions, is there still no hard evidence? Marine biologist Zachary Wallace knows, but the shock of his near-drowning as a child on Loch Ness have buried all memories of the incident. Now, a near-death experience suffered while on expedition in the Sargasso Sea has caused these long-forgotten memories to resurface.
