Oh, the best lists are beginning to arrive as we approach 2020. This list from The Guardian is heavily British, so some of the books haven’t been published in the U.S., but I thought it was worth a look. I would dispute the inclusion of some of the titles, but that’s what makes it fun.
Another list, from LitHub of the best books of the last ten years. I read most of the titles listed, enjoyed several, found some of them meh, and others unreadable. Reading is for pleasure so find the ones you enjoy.
