'Apocalyptic sci-fi at its best... The action is anything but frozen' DAILY MAIL. WITHIN THREE MONTHS, ICE WILL COVER THE EARTH, AND LIFE AS WE KNOW IT WILL END. It was the last thing we expected, but the world is freezing. A new ice age has dawned and humanity has been forced to confront its own extinction. Billions have fled the glaciers, crowding out the world's last habitable zones. They can run from the ice, but they can't escape human nature: a cataclysmic war is coming. In orbit, a group of scientists is running the Winter Experiments, a last-ditch attempt to understand why the planet is cooling. None of the climate models they build makes sense. But then they discover an anomaly, an unexplained variation in solar radiation... and something else. Close to the burning edge of the sun, they catch a fleeting glimpse of something that shouldn't be there... Suddenly humanity must face the possibility it is not alone in the universe. And the terrifying possibility that whatever is out there may be trying to exterminate us. 'A complex, multi-stranded narrative spanning 700 pages that reads like a superior collaboration between Dan Brown and Michael Crichton' THE GUARDIAN.

The Long Winter is over. We survived. But only just. On a ruined world, we rebuild, watching the sky, waiting for any sign of their return. With only nine million survivors from a population of billions, humanity's survival is far from guaranteed but with the glaciers receding, there is now, at least, a chance. But out on the edges of the solar system, beyond Neptune's orbit, three vast asteroids have broken free from the Kuiper Belt and started the long fall towards the Sun. In two years time their trajectories will converge on Earth. We have to face the truth: they are back. And this battle will be to the very end. As humanity prepares its last stand in space and on the ground, it splinters. In our darkest hour, factions form and trust evaporates. And yet not all is lost. Dr James Sinclair has a plan that could ensure the species' survival, but it comes with enormous risks. Implementing it means navigating a course between two deadly enemies. One thing is certain: Sinclair's gambit will change the human race forever.

The last survivors of the human race escaped a ruined Earth. Eos seemed perfect at first. Warm. Hospitable. Safe from the grid. But everything isn't as it seems.The planet's first settlers have disappeared. As Dr James Sinclair digs into the mystery of the lost colony, he discovers a series of spheres buried on Eos. Are they the key to finding the lost colonists? Or are they responsible for their deaths? Or are they a sign of something else altogether?Just as James is unravelling the secrets of the spheres, a storm hits Eos, and in the middle of the chaos, a new danger emerges – a threat no one saw coming...With time running out to save the colonists, James and Emma will face their hardest choice yet in the final pulse-pounding instalment in The Long Winter trilogy.Praise for A.G.

In Antarctica, a groundbreaking experiment will change everything.Dr. Laura Reynolds had it all.A job she loved. The respect of her peers. Student debt she was slowly chipping away at.And one day, she lost everything.She saw the wrong thing — a colleague’s mistake. And to escape, he framed her.To avoid prison, Laura reluctantly agrees to join a secretive research project in Antarctica, where she hopes to keep practicing medicine and someday get her life back.

From the bestselling author of Lost in Time and Quantum Radio comes a new mind-bending thriller: a group of strangers with tinnitus begins seeing numbers — numbers they soon realize are a code that will change the world.Alan Norris has lost everything. Except for his daughter. And he’s willing to do anything to protect her. The day of his wife's funeral, as he’s walking to give the eulogy, the ringing in his ears starts. His tinnitus began when he was in the Marines, the day a roadside bomb went off. Usually, it's a low whine — a tea kettle that never quite boils. But as his prosthetic and his good leg sink into the soggy grass, the ringing changes. That afternoon, the ringing only he can hear sounds like three jagged rocks dropped in a tin can and shaken. When the rattling hits a crescendo, he sees a series of numbers: 12122518914208. He assumes it’s a stress reaction. A hallucination. He’s wrong about that. And several other things. The ringing and the numbers are a mystery, but the worst part is that when that unseen hand shakes the can, Alan begins to lose time. A few minutes at first. Then longer. Until one night, he wakes up next to a dead body. He could call the police. Or run. He doesn’t do either. Because he doesn't know what happened to his daughter during the time he lost, leaving him no choice but to dig deeper. Alan soon discovers he's not the only one seeing the numbers. And that the sequence is key to a conspiracy with far-reaching consequences. For him and the entire world.

Geneticist Kate Warner and intelligence agent David Vale may have a chance to avert the looming catastrophe, but only if they can decode the secrets of the Atlantis Gene and unlock the truth about humanity's origins.
