Rainbows End [Hardcover]

I've been a big fan of Vinge for a long time, but more so after "a fire upon the deep". His last two were big space opera plots with a dash of new technology thrown in, more on the ian m banks thread. This novel goes in a very different direction and moves very strongly into the thriller rather the science fiction territory. The trends explored here, fully immersive technology, difficulty of multi generational family relationships, knowing just who your allies are in a much more connected world and the challenge of sudden technology step change, made this some what jerky in places.
However I found on rereading , a few months later the book grew on me and the multi layer, multi threaded story started to become more coherent.
Vinge's background, as a professor of computing science shines through in places, particularly in his assumption of audience understanding of technology challenges.
Finally there is a real juicy hook here in the presence of a complex "AI" character just crying out for a sequel. What are you "rabbit?"
I'd say "persevere with this book" it rewards persistence

No, I haven't mis-typed the title. There's no apostrophe, and one of the characters in the book has a little grump about it. The background and the people are in many ways far more interesting than the story itself. The world that Vinge has built has a fair amount in common with some of his other work, in particular the ubiquitous networked computing that he elsewhere calls "localisers". The theme of surveillance is also something that readers of, eg, A Deepness In The Sky, will be familiar with. And what's more, a lot of the background is a reasonable extrapolation from the present day. Networked computing is becoming ubiquitous; augmented reality is in use in some industries and being played with by hackers the world over; and of course the Surveillance State is growing a-pace, all in the name of Stopping Terror - a justification that they use in this book too. Thankfully the Secure Hardware Environment that Vinge postulates doesn't yet exist, and something similar has proven to be a failure in the market so far, but I'd not be particularly surprised if something like it were to appear again soon. So the story is firmly rooted in the present.
The actors are believable too, if pushed just a little to extremes. But such is the nature of heroes and villains in all fiction. As is often the case with good fiction, I was left at the end of the story wondering what their lives would be like afterwards.

There are a few problems though. The "belief circles" - something that other reviewers have described as a blend of wikipedia, second life and augmented reality - don't make much sense to me, and while they only play a minor part in the story, serving as a distraction the bad guy manipulates to keep the "good" guys away, they could have done with more fleshing out, in particular explaining why individuals choose to put so much effort into them. But the biggest problem is that to understand all that goes on you need to understand public key encryption and authentication. And virtually no-one does. I do though, so it didn't spoil my enjoyment of the story, and with the one caveat that you should be at least on speaking terms with public-key crypto, I recommend this book. The biggest disappointment was that it was all fiction - one of the "belief circles" that Vinge invents is based on the fiction of one "Jerzy Hacek" who unfortunately doesn't exist. Shame, cos the Librarians Militant sound wonderful.

I wasn't disappointed in this at all. I thought it was great. I just wish he was a bit more prolific although I'd rather have quality, like this, than quantity. It's an extrapolation of "Fast Times At Fairmont High" from
his collected stories and "Synthetic Serendipity" , which are both great short stories.
