From the back of the book:
Their greatest fear was contaminating an ancient Antarctic lake, buried beneath the ice for millions of years. They little knew the catastrophe they were about to unleash.

Welcome to the high octane world of Olivia Wolfe. As an investigative journalist, Wolfe lives her life in constant peril. Hunted by numerous enemies who are seldom what the first seem, she must unravel a complex web of lies to uncover an even more terrifying truth.

From the poppy palaces of Afghanistan and Antarctica's forbidding wind-swept ice sheets, to a top-secret military base in the Nevada desert, Wolfe's journey will ultimately lead her to a man who would obliterate civilisation. She must make an impossible choice: save a life - or prevent the death of millions.
