Swann's Way does not, by any means, possess a plethora of plot. In fact, it has very little plot to speak of. Let's establish that right from the start. If your inclination is towards a story that is driven by a complex and engaging plot, then this is not the book for you. You should look elsewhere. What this remarkable work does instead is to loop in and around specific topics, both in the narrator's life and in the life of Swann. It delves into these topics with such meticulous and minute detail, presented in flowing prose that seamlessly transitions from one moment to the next, continuously looping around the events under consideration. And it must be emphasized that the writing is exquisitely beautiful.
