Man on Edge — Humphrey Hawksley

A tense and twisting espionage thriller involving state secrets, lethal assassins and the threat of a new Cold War.

Trauma surgeon Carrie Walker is taken aback when her estranged uncle makes contact out of the blue. Senior Russian naval officer Artyom Semenov claims to be in possession of an explosive piece of information which he is offering to share with the West. But can he be trusted?

Travelling to Moscow undercover to meet with Semenov, Carrie finds herself stranded when the carefully-planned operation goes catastrophically awry. In grave danger, there's only one person she can turn to for help: her former fiancé, Major Rake Ozenna of the Alaska National Guard.

Aware how vital it is that he reaches Carrie before others do, Rake knows he's pitted against a powerful and lethal enemy. But is it a rogue agent - or the Russian state? As preparations gather pace for a high-profile NATO exercise off the Norwegian coast, Rake must act fast if he is to prevent a global catastrophe.
