Just finished "Night Film" by Marisha Pessl. I loved her first book, "Special Topics in Calamity Physics" (which I unsurprisingly bought because of the title), and this was good too, just not as much. The author pulled two old tricks in quick succession at the end, leaving the end a bit of an anti-climax. But it was probably the best way out.
Before that was "The Killing Moon" and "The Shadowed Sun" by N K Jemisin. These are fantasies, but unusual ones. For a start, there's only two in the series, and it's not one book split in two: the second takes place a decade after the events of the first. For a second, the basis of their magic is dreams. Not an original idea, but a very rare one, and heavily influenced by Ancient Egyptian theology. The first book is definitely the better of the two. The second reminded me a little of Robin Hobb. I consider that a complement, but I'm aware that some here do not. These two are good enough that my next visit to a book shop will feature her earlier books (Jemisin, not Hobb - I already have most of those).
Before that was "Blunders of our Governments" by King and Crewe. Its exactly what it say on the tin: the story of some of the worst government ****-ups since 1979 up to about 2013. Some are dealt with in great detail, and are the sort where you struggle to understand how the people concerned could not see what was about to happen. There a later section on why these catastrophes happen, but that's rather dull compared to watching politicians falling face-first in a cow-pat of their own making.
Now I've just started "Republic of Thieves" by Scott Lynch.
