* Longlisted for the Wilbur Smith Award for best published novel. *

In the near future, a new ice age has begun.

Humanity stands on the brink of extinction.

Desperate for answers, scientists send probes into the solar system to take readings. Near Mars, they identify a mysterious object moving toward the Sun. Is it the cause of the ice age? Or could it be humanity’s only hope of survival?

With time running out, NASA launches a mission to make contact. But the object isn’t what anyone thought. In the dark of space, alone, the team makes a discovery that will change the course of human history—and possibly end it.

Filled with real science and fascinating details, Winter World is that unique blend of fact and fiction that could completely change how you see our planet—and humanity’s future. For those intrepid souls starting this bestselling trilogy, be warned: you may well be up late into the night turning the pages.
