Modern, well-written books?

I've read my share of well-written books from the 1800s up until the 1970s or 1980s, but I'd like your suggestions for any well-written books from the last 20 years or so. And I've read my share of books with well-written stories built with poorly-written paragraphs and/or sentences, so I'd like your suggestions for books with well-written stories, paragraphs, and sentences. Any genre is welcome, but for what it's worth I'm putting this question to the community because I realized most of the books I've finished in recent years were written between the 60s and the 90s.
