Ex-Green Beret Major Nate Walker left war with many regrets. His men were betrayed and dishonorably discharged, and now he's determined to take down the arms dealer who destroyed their lives. To do that, he needs to stop Sarah Munro from solving an unbreakable cipher — or one of his men will die. His unexpected feelings for the strong-willed woman only complicate things.

Now, Nate is caught in the middle of a war between his former Colonel and the two enemies gunning for Sarah. All of them are trying to use him for their own ends. Will he be able to save the woman he loves...or lose it all?
