Speaking of science fiction, I've just been rereading Ken MacLeod's Fall Revolution [0] series. Great stuff, and I totally agree with Kim Stanley Robinson's assessment: "He is writing revolutionary SF. A nova has appeared in our sky."

Thanks! I just bought The Star Fraction purely on your recommendation... I find gambling like that pays off big, sometimes.
To return the favor, I recommend you try Blindsight and its sequel Echopraxia, by Peter Watts. Those were two of my favorite books of 2015 (the books are older, but I only found them this year).
I just read both of those earlier this year, based partially on recommendations on HN.
Speaking of book recommendations, try almost any book reviewed in Jo Walton's collection of essays: *What Makes This Book So Great?. I read and bought about the first half-dozen or so that I hadn't already read, and there was only one that I didn't enjoy thoroughly, and more because it was too much of an emotional downdraft than because it was badly written, which it wasn't at all.
