Hearts in Hiding (Love Inspired Historical)

Engineer Edie Michaels loves her life-she has a good job, close friends, even a chance at romance with former soldier Beau Daniels. But she could lose everything if her secret comes out...that she's the German daughter of a devoted Nazi. And when her father sends spies to force her loyalty, everything Edie values is at risk. 

Time in a Nazi POW camp changed army medic Beau Daniels. When he discovers a letter of Edie's written in German, he can't help his suspicions. Is she truly the woman he's started to love? Or has she been the enemy all along? With Nazis on Edie's trail, the pair must fight for truth, for survival-and for love.
