Anna Dahlberg grew up eating dinner under her father’s war-trophy portrait of Eva Braun. Fifty years after the war, she discovers what he never did—that her mother and Hitler’s mistress were friends. The secret surfaces with a mysterious monogrammed handkerchief, and a man, Hannes Ritter, whose Third Reich family history is entwined with Anna’s. Plunged into the world of the “ordinary” Munich girl who was her mother’s confidante—and a tyrant’s lover—Anna finds her every belief about right and wrong challenged. With Hannes’s help, she retraces the path of two women who met as teenagers, shared a friendship that spanned the years that Eva Braun was Hitler’s mistress, yet never knew that the men they loved had opposing ambitions. Eva’s story reveals that she never joined the Nazi party, had Jewish friends, and was credited at the Nuremberg Trials with saving 35,000 Allied lives. As Anna's journey leads back through the treacherous years in wartime Germany, it uncovers long-buried secrets and unknown reaches of her heart to reveal the enduring power of love in the legacies that always outlast war.
