Will they arrive for Christmas? Will they arrive at all? Their lives are about to change forever. Prepare to be shaken.

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. 

Liam and Hannah continue their dangerous journey, but their every step is dogged by a deadly adversary. Hunted and exhausted, will they have what it takes to get home?

His sister, Kristi Boone, is a Doctor of Veterinary Medicine known for being attune to the exotic animals within her care. At first, the changes in the animals' behavior are subtle...until they aren't.

When the end of the world arrived, it came not with a bang, as most expected, but with more of a "pfft" instead. Humanity has been torn asunder and brought to the edge of total annihilation in less than an hour. For those who died, it was a quick death, so fast that their brains didn't have time to process the pain signals from their nerves. For those who survived, the true horror is about to begin as they struggle to not only stay alive, but come to grips with the shocking realization about what - and who - was responsible.

In the middle of the coldest winter on record, a super EMP destroys the power grid. No electricity. No cars or phones. Worst of all, no heat. The country is plunged into instant chaos.

Hannah emerges from her underground cell into a hostile winter landscape with no way to call for help, no vehicle that will drive, armed with nothing but the clothes on her back and her own determination to survive.

Throughout the millennia, mankind has faced epic floods. Evidence shows that the sudden reversal of the planet's magnetic field, a fast pole reversal, had a profound impact on climactic conditions. What was once frozen is now melted. The rising sea levels had to go somewhere. In past civilizations, man persevered because after these floods, the waters always receded. Until they didn't.

For eons, since the formation of our planet, Earth’s magnetic poles have reversed. Powered by the machinations of her spinning iron core, coupled with the hot liquid that has churned around it since the planet’s infancy, this geologic wonder has been occurring without much fanfare, until now. A geomagnetic apocalypse is descending upon humanity. It’s a catastrophic event caused by the Earth’s magnetic field growing restless. And now, the changes are accelerating at an astonishing rate. What happens when the magnetic field grows weaker?
