The mind-blowing third book in the Black Heart series.

Hard-nosed blogger Carmine Cleary lives in a frigid and snow-bound Los Angeles in the mid twenty-first century. It's been more than ten years since the news broke that the earth was spiraling far out of its orbit, dragged by a celestial force known as Dark Matter. The ongoing catastrophe has been nicknamed the 'Big Chill'.

Scientists understand what's happening, but are powerless to stop it. In less than a year, every living thing on the surface, billions of humans and trillions of other life forms, will freeze to death. The news has sparked a desperate rush of humanity to the warmer equatorial regions.

Like everyone else, Carmine has come to accept that he will die of the cold or starvation. But while investigating the death of a billionaire philanthropist, he stumbles on an incredible secret known only to a select few - that a mysterious secret society has been constructing a massive installation deep underground, not far from the city of San Francisco.

A tiny fraction of humanity are planning to survive the Big Chill.
