Now this might sound weird as most books probably aspire to some kind of character depth, but I search for books where a main portion of the book is internalized thought, reflections, rememberance, speculation and so on.
Maybe some examples of books that I do think do that well:
Panenka – Rónán Hession
The Remains of the Day – Kazuo Ishiguro
Atonement – Ian McEwan
Eurotrash – Christian Kracht
Stoner – John Williams
Thank you!
