The Berlin Letters

When Luisa Voekler discovers a secret cache of letters written by the father she has long presumed dead, she learns the truth about her grandfather's work, her father's identity, and why she has never progressed in her career. With little more than a rudimentary plan and hope, she journeys to Berlin and risks everything to free her father and get him out of East Berlin alive. As Luisa and Haris take turns telling their stories, events speed toward one of the twentieth century's most dramatic moments.
