A book can take you on a good journey and the beginning is very important. Whether you really will let yourself dive deep into it or whether you stay at the surface.
As an example I have chosen Hermann Hesse's "Morgenlandfahrt" (English title: "Journey to the East"). I remember it as one of the novels that really kept my attention from the first page. It starts off as follows: "It was my destiny to join in a great experience. Having had the good fortune to belong to the League, I was permitted to be a participant in unique journey. What wonder it had at the time! How radiant and comet-like it seemed, and how quickly it has been forgotten and allowed to fall into disrepute. For this reason, I have decided to attempt a short description of this fabulous journey, a journey the like of which had not been attempted since the days of Hugo and mad Roland."
