Twice I have read
Voyage au bout de la nuit by Louis-Ferdinand Céline. I read it in French but it has been translated into English as
Journey to the End of the Night. Unfortunately the book is unavailable legally as an e-book.
I bring this book up because I have very conflicted feelings about it. It's about a man who joins the French army during World War I and his experiences following the war. It's a very angry book, filled with tirades that are at times racist. There are graphic scenes of violence that can provoke physical discomfort. The author is a real virtuoso of swearing and colloquial language.
It's not the sort of book I typically read, where the characters wallow in such blackness and nihilism. And yet I find I enjoy the book because the author is so skilled with language and with painting vivid images that linger in the mind.
