The Book of Tea by Okakura Kakuzō. Philosophy, history, and aesthetics in a 1906 treatise on tea.
Hard-Boiled Wonderland and the end of the world is the most scifi Murakami. Wonderful stuff. Then read all his others. Knausgård 'My Struggle' is a very compelling personal story (5 volumes!) where you get inside his head. Not a novel. Ursula Le Guin - the Lathe of Heaven. More scifi.
Can’t go wrong, good vacation reads. M

It's a fun series. If you are a fan of the show I think you really should read the books. Even if you haven't watched the show I think most people will enjoy the books. They are page turners and I've stayed up way to late almost every night since I got them.
Kurt Vonnegut's novel Slaughterhouse-Five has also faced censorship for its political message. Published in 1969, Slaughterhouse-Five is one of the most censored books in recent years.
