An ebook short story set in the coldest place on earth, perfect for fans of Dan Brown, Dan Simmons and Alistair MacLean.

Utgard: a tiny island at the frozen edge of the world. Home to scientists, oil men, and the occasional polar bear. For Andy MacDonald it's the most awe-inspiring place on earth: isolated, beautiful and pristine. Mac has always respected the Arctic. He's always understood how dangerous it is.

Until the day that a beautiful woman emerges from a whiteout, claiming to be nothing more than a lost environmental activist. Before long Mac is caught up in a dangerous game of cat and mouse. And he's about to find out exactly how deadly the Arctic can be.

'Polar Vortex' takes place six months before ZODIAC STATION, the novel Chris Ewan calls 'thrilling and immersive'.
