The world's largest oil reserve lies buried beneath Arctic ice. And one man will kill to claim it, even if it means triggering a global catastrophe. When scientist Richard Cathey discovers an energy source that could reshape the global economy, he becomes a target. His sister Evelyn, a Canadian intelligence agent, races to unravel a conspiracy that threatens to ignite an international powder keg. Alongside CIA operative Blake MacKay, she must stop exiled Saudi Prince Awadi Salib from drilling a reserve that sits atop a massive magma chamber, a disaster that could flood coastal cities and destabilize the planet. Mercenaries are hunting them. Political alliances are fracturing. And a thin layer of rock is all that separates untapped oil from environmental apocalypse. Blake and Evelyn face an impossible mission: prevent a drilling operation that powerful nations want completed, expose a conspiracy that reaches the highest levels of government, and survive long enough to stop a catastrophe that will reshape the world before it's too late. This is espionage at the edge of the world. Where the cold kills as fast as bullets. And where one wrong move could trigger the end of everything. Beyond All Measure delivers a heart stopping thriller that combines the geopolitical intrigue of Tom Clancy, the environmental stakes of Michael Crichton, and the breakneck action that fans of Matthew Reilly and Mark Greaney demand.
