The book is intended for adults who grew up in emotionally harmful or unstable family environments, as well as individuals currently navigating difficult relationships with parents or relatives. It adopts an explanatory and reflective approach, combining psychological concepts, structured insights, and practical discussions on boundary setting, limited or no-contact decisions, emotional healing, and personal recovery, presenting toxic family dynamics within a clear and educational framework.
