Book excerpt: Is the history of a dangerous love affair destined to be repeated? At the height of her career, opera singer Katherina Marow is brought crashing down by her father's suicide. Among his effects, she finds his wartime journal and reads the heart-wrenching entries of a soldier in Russia and in war-torn Berlin. She learns the crimes and secrets her father harbored, but cannot condemn him, for while she discovers his demons, she is facing her own. The stage-world she lives in draws her into a lawless ecstatic realm, and she is tempted, as he was, by forces which could destroy her. Has she too made a devil's pact? And if so, will she pay for it, as her father did, with her life?
