City of ShadowseBook - 2005
But Anna is being hunted. Or so she claims. At first Esther believes Anna's fears to be just in her imagination--until innocent people around them begin to die. Together with a German police officer, a dogged inspector named Schmidt, Esther tries to discover who wants Anna dead--and why. Yet the deeper she and Schmidt dig, the more they realize that their own lives are at risk.
