Ring Around the Sun — Harper Fox

MI5 agents Marina Griffin and Leo South are made to be together. But their mission's-end encounter with Ashkeloi gypsies in the Russian forest reveals a terrifying prophecy â€" a fate that will tear them apart, and re-echo into the lives of their sons, John and Mike.

Thirty years later, a deadly climate shift has opened up a seaway through the Arctic, and nuclear war is imminent as the global superpowers make a grab for the oil reserves suddenly exposed. Like everyone else, Mike and John just want to ride out the storm and protect the people they love, especially their boy Quin.

But love isn't enough when the stakes are this high, and Mike and John too are in the grip of a destiny they can't avoid. Summoned from their Glastonbury farmhouse to the office of their ex-boss, James Webb, they discover not only the truth about their heritage but the forces they will have to encounter if the war for the Arctic â€" and the future of humanity â€" is to be won.
