Scot Harvath is having his best summer yet。 With a cottage on the fjord， a boat， and his beautiful girlfriend Solvi， he's got everything he could possibly want。 But out of vacation days and long overdue back home， American'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 cafe， 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 never imagined and pushed to a limit few human beings could endure。

If he succeeds， he'll walk away with everything。 If he fails， the United States and its allies will be at the mercy of one the world's dangerous actors。
