I've been reading Iain Bank's the culture series recently and it's p good. There are 10 books though so some of them are better and some are worse ofc.
Robert Jordan's wheel of time series is also OK, it's like 14 books too so there are good and bad books here as well. I think i've read up to book 9 and the books are good at least until then.
James Clavell's asian saga is very good series too, the chronologically first book, shogun, is probably one of my favourite books.
If you are looking for non-fiction i can recommend Max Tegmark's book on AI, although it is pretty technical.
Haruki Murakami's book about running is interesting and quite motivating.
I also read a really good book about ancient languages by Ola Wikander not too long ago but i don't think it's translated to english. The book was easy and fun to read despite difficult language stuff so if you find books by him they might be good.
