The Echo Creator

When twenty-seven-year-old Mark Schlueter is involved in a car accident, his older sister Karin, against her will, returns to her hometown to care for her brother. However, when he comes out of the coma, he believes that she has been... replaced by a completely identical doppelgänger, who may wish him harm—despite looking, acting, and speaking like his own sister. Desperate, Karin seeks help from a renowned neurologist, a true star in medicine, Gerald Weber. He arrives, seizing the opportunity to study a rare case of Capgras syndrome—a rarely encountered delusional disorder. But everything turns out to be even more complicated, and constant interaction with the patient begins to affect the doctor's own mind. Meanwhile, Mark, armed only with a strange note left in his hospital room by an unknown person, attempts to uncover what happened the night of the car accident. The truth about it will irrevocably change the lives of all three.
