She smiled at the men who killed her brother. Then she destroyed them.

Stockholm, 1942. While Europe burns, neutral Sweden has become the world's most dangerous chessboard—a city where German, British, Soviet, and American spies circle each other in an endless shadow war.

Karin Lindqvist is a celebrated actress with a secret: she works for Swedish intelligence, gathering information from the Nazi officers who court her at diplomatic receptions. It's her way of avenging her brother, torpedoed by a German U-boat in the North Sea.

But when a German pastor arrives with an extraordinary proposal—a conspiracy to assassinate Adolf Hitler—Karin is drawn into a game far more dangerous than anything she's played before.

Three intelligence services want her loyalty. One wants her dead. And the man she loves doesn't know who she really is.

As the plot against Hitler builds toward its explosive climax on July 20th, 1944, Karin must make impossible choices. Betray the people who trust her—or watch the resistance die. Protect her unborn child—or protect the secrets that could end the war.

In a world where everyone wears masks, the deadliest question isn't who can you trust?

It's who have you become?
