This was a confusing book. Despite being very well written and evocative, I often had absolutely no idea what was going on. It’s the opposite of an infodump: Rajaniemi just tosses out terms left and right and assumes that the reader will understand or figure out what they mean. For some of them, I could, and for others, I really couldn’t. It made fight scenes, master plans, and detective investigations much harder to follow than they should have been (and sometimes I couldn’t figure them out at all), because I had no real idea what any of the technobabble meant. I found it took a lot more brainpower to read than many of the other books I’ve finished lately. Final verdict: I enjoyed the book enough to read to the end, but not enough to read the rest of the series.
