All the Light We Cannot See has been constantly recommended to me, it was a top book of the year a couple years ago, as well as a Pulitzer Prize winner. What put me over the top to finally add this to my reading list was glancing at a few of the reviews for The Nightingale which said this book was better than that one in the genre of World War II historical fiction. To that point I think I agree.
All the Light We Cannot See is supurbly written not just in terms of prose, but in terms of style by mixing narrators and time in an interesting and entirely clear way. I enjoy short chapters for whatever reason, and this book basically had large chapters broken up into tiny chapters which made the book easy to pick up at any time without having to worry about finding a decent stopping place. I read this a little slower than other books, which allowed me to really think about what was going on a bit more. I think this helped me to really appreciate the plot unfolding moreso than if I tried to rush through it.
All that being said, I do not really have a lot to say about the book beyond that it was great. I did not really have too many deep philisophical thoughts while reading it, at least to the point that I remember them and want to comment on them here. I recommend reading the book, that is about all I have to say about it.
