Halting State by Charles Stross
Might contain spoilers.
I was less impressed now than in 2014, but this is still a decent (if slightly forgettable) book with no major flaws, not to mention an enjoyable one. Its depiction of the connected future is impressively authentic and believable. Prescient, too, considering the distributed database stored on people’s phones, much like a blockchain. The permanent use of augmented reality glasses sounds exhausting to me.
The plot is somewhat confusing, at least early on. It takes a long time to start making sense, not just when it comes to the significance of the events but also in terms the thrust of the story.
I unfortunately can’t say I enjoyed the sequel (Rule 34) much when I read it a while ago.
