The german newspaper Sozialistische Tageszeitung reviewed Fathers Big Secret
in a special Frankfurt Book Fair supplement. The book will be on sale in Germany next week.
Among other things, the review says that the book is unique, a book like this has never been written before, this an unbelievable an disgusting horror tale.

The paper then goes on to quote a short example from the book were the children ar scolding their father for cannibalism:

But dad, you know it's wrong to eat people, Right? I said softly when we had calmed down after hearing the
story about the teacher's cruel fate.
– Wrong to eat people? dad replied. Is it wrong to go to war and ride your bike on the sidewalks then? He gazed out of the window, deep in thought. It may be wrong to eat people but nobody follows the rules of right and wrong.

This sentence captures the essence of the book, says Sozialistische Tageszeitung. The paper then goes on to explain the book with the sub-title as a starting point; Book for children with parent problems. It states that radical books like this are necessary, children have become numb from to many terrible things in the modern world. The book works like a tough medicine, helping children who have experienced violence and difficulties feel better about themselves.
