I am currently reading it and find the prose really good with the main focus being to remember his old feelings and thoughts from back then. There is really no overarching plot or structure which I feel can make it a bit hard to keep going as there is no goal outside of the interesting ways that he describes feelings and patterns of behaviour/thought.

I found Swann's relationship to Odette really interesting in how much of his love comes from him and doesn't really have that much to do with her and her actions.

I have a few I liked Darwin and an Emergence of Evolutionary Theories of Mind and Behavior by Richard J Roberts from a history of Science perspective.

For some more technical biology books Randomness in Evolution by John Tyler Bonner was interesting and Chance and Necessity by Jacques Monod.
