Yumi and the Nightmare Painter was a lot of fun. I loved the cyberpunk-ish setting of Painter's world.
I also read Consider Phlebas, which is the first book in The Culture series. It's like an inverse space opera. The protagonist is a shape-shifter who is perfectly willing to murder someone in cold blood and assume their identity and is fighting for the actual bad guys (religious zealots who have no problem genociding the lesser species). Pretty much none of what happens in the book actually has an effect on the wider setting (a decades long war where hundreds of billions die and dozens of planets are destroyed; and that is regarded as a short, small war). Even the main antagonist who is on the side of the explicit good guys is disillusioned with her cause to an extent.
For the first two thirds I was waiting for the plot to really get going, then the final third is just one gut punch after another. I highly recommend it for anybody who wants to feel totally empty inside.
Now I'm reading The Sunlit Man, the last of the Sanderson secret projects, and it also seems like it's going to be pretty grim. I'm only about a quarter of the way in, but this already feels like things are going to go sideways, extremely fast. I figured out the protagonist pretty quickly, and I'm dying to know what happened to Roshar in his (now) extremely distant past. Hopefully Sanderson drops a few more hints throughout the book. I'm also considering having myself cryogenically frozen until December so I don't have to wait too long for Stormlight 5.
