Scot Harvath is having his best summer ever. With a cottage on the fjord, a boat and his beautiful girlfriend Sølvi, he has everything he could possibly want. But out of vacation days and long overdue back home, America’s top spy has a decision to make --- return, or submit his resignation. When his deadly past comes calling, though, he’ll be left with no choice at all. Leaving his favorite Oslo café, Harvath watches as a ghost climbs out of a taxi --- a man he killed years ago, halfway around the world. How is he still alive? And what is he doing in Norway? In a race against time that will take him high above the Arctic Circle, Harvath will be tested in ways he has never imagined and pushed to a limit few human beings could ever endure.
