Four years ago, she saved his life. Now she has to kill him.

Cairo Elizabeth Corbyn died four years ago, incinerated in a blast that left no survivors - except for the Navy SEAL she saved. That's what Mossad believes, and Kai is content to live the lie. She's created a new life for herself and put the past behind her.

Until now.

CIA Special Agent Dean Ryder is used to facing an enemy he can't see. So when an assassin is hired to kill him, he considers it just another battle to be fought. Until he sees the shadow of a woman he knows is dead.

As a traitor leaks the locations of agents around the globe, Dean races to find the spy in Langley before an assassin puts a bullet in his head. But Kai has never missed a target in her life.

And she's not about to start now.
