Scarlett Young is a 30-year-old psychiatrist who, after monotonous cases, gets one that doesn't get rejected so easy - the case of a serial killer. At first, it seems like a black-and-white case, but what will happen when Scarlett starts to doubt it all? And who she can trust - Her mentor, her detective crush or a cunning psychopath behind the glass? Should she believe her own instinct or is the cunning villain playing with her mind all along? SORRY IF THERE ARE SOME GRAMMAR MISTAKES, ENGLISH IS NOT MY FIRST LANGUAGE. Cover: SweetAngel126
