Kindle. Prompted by an intriguing review by Hari Kunzru in the New York Times, which is unfortunately superior to the source material. Korean sci-fi. The writing/translation is fine but I can't say I totally got it. Most of the ingredients are cyberpunk staples: the zaibatsu, the AIs, the ultra-competent violence, and of course the space elevator takes the concluding action to something like a space station, all just like Neuromancer. There is some nasty retconning in the final movement. Cinematographic, of course. I have no idea what the point was.
The publisher's summary at Goodreads says it all. Otherwise I didn't find too many reviews.
