The new Cold War is about to go hot.

#1 New York Times and #1 Wall Street Journal bestselling author Brad Thor is back with his most intense thriller yet.

Scot Harvath is having his best summer ever. With a cottage on the fjord, a boat, and his beautiful girlfriend Sølvi, he's got 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 is tested in ways he has never imagined and pushed to a limit few human beings could ever 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 of the world's most dangerous actors.
