Family creates security and connection, providing protection and support in times of need and distress. But what happens when love suddenly turns into hate? How can conflicts over custody or suspicions of abuse become a nightmare in which children suffer and lives are destroyed? In his book "Familienbande Krass," renowned psychological expert and long-time professor Prof. Harry Dettenborn tells ten gripping stories that reveal the double meaning of the term family ties. He illustrates how irrational and sometimes criminal actions can turn life into a nightmare, where beloved children are tormented and shared property becomes a trap of poverty. Experts are then commissioned by courts to propose solutions that prioritize the well-being of the children while respecting the rights of the parents. But how can they help? In each of the ten stories, readers closely follow how psychological expert Dr. Rother interacts with the parties in conflict, how he assesses the mixture of hate and violence, lies and delusions, child abuse, sexual abuse, and allegations of abuse, and what solutions he proposes. This narrative non-fiction book highlights the importance of recognizing and resolving conflicts within families early on and the consequences of lacking the necessary insight into problems and willingness to change. A book that encourages affected families and shows through the stories of Prof. Harry Dettenborn that they are not alone with their problems.
