One step forward and two back

A somewhat different birthday present - a return to a previous life through hypnosis, does not catapult Heinz to the Middle Ages as planned, but to Graz in the 80s. And he is not only not himself, but his uncle Wolfgang! Like an invisible shadow, he sticks to his fateful moments for decades. Through his turbulent events, Heinz may be able to make a profit for his own life... Is the book fiction, biography or a guide? You decide, dear reader!
