How Do You Maintain Your Identity When the Lines of Reason Become Blurred? The year is 1968, and the Vietnam War is in full swing. Dr. Bridget Castle, a neurosurgeon in Boston, handles the victims of anti-war protests, the casualties of war, and the stress of being a woman in a male-dominated profession with ease. For more than twenty-three years, Bridget has walked in the shoes of a girl killed in the Blitz, blurring the line of when her own identity as a German-born Jew ended and when she assumed the role of changeling. If not for her childhood diary to remind her of all she endured, she would be completely successful in taking on the memories of the girl she replaced.

But when the son of a Nazi soldier is placed in her care, she finds herself unable to deny her past any longer. The last time Bridget had to stare into the face of evil, she learned, despite losing everything, just how strong she was. Now that the ghosts of her past have awakened, will she be strong enough to avenge the life that was stolen from her?
