In the future, humanity is watched over, arguably controlled by AIs, and only a small fraction of people live in what we think of as the "real" world... many citizens are digital copies, living in simulations of reality, albeit with a human lifespan. An agent of the government rescues one of these digital copies from an illegal simulation used for torture fantasies, and the two go on a quest to find the creator of the sim and bring him to justice. And in deep space, a human is sent to investigat ...more

There were moments in this book that captivated me. I'm interested in subjectivity, identity and the construction of reality and experience...but ultimately I just couldn't stick with the book. I skimmed the last part. It isn't that the writing is bad or anything (hence two stars rather than one) but I lost interest. I think it has something to do with the narrative structure; the shifts in point of view characters and of time frames contribute to a feeling that the ideas haven't been explored t ...more

Virtual worlds, in which personality constructs and AIs live, are now considered as real as the tangible, "atomic" world we live in today. The story follows social worker Judy and one of her charges, Helen, as they traverse the two realities in search of answers. Their search gradually broadens in scope until at last they discover what happened at the edge of the known galaxy two decades ago. The characters are prickly, complex and believable; I particularly liked Helen, whose last memories were ...more

In a not so distant future humanity has given up control of it's every day lives to A.I. In order to ensure its survival, peace and harmony. This work of fiction explores the ramifications of this, such as, if we give up our free will are we still human. If free will is in the hands of an A.I. were program and analog replace spirit; passion, morals, ethics. (Think "i Robot") If we make a digital copy of ourselves, and live in a digital world are we still human?

The second novel in a science fiction trilogy, set in a 23rd century in which human affairs are managed by AIs and virtual worlds (some of which simulate our own exactly) exist, in which virtual people whose personalities have been copied from flesh-and-blood people live out their lives.

A few plot elements:

1) a woman named Helen is rescued from an illegal virtual world in which she, and many copies of her, has been used as the victim for perverts living out their torture/rape fantasies. Now that

Another very good hard SF book. This story follows on from Recursion but other than sharing the same universe it does not really continue the story of Recursion. However the third book does continue this story.

Again this is very computer techie hard Sf. It takes a very interesting look at the ideas of real, or in the book's terminology atomic, people, personality constructs (copies of atomic people running in virtual realities) and AIs and all their relative rights as unique individuals. This is

This is yet another living-as-a-virtual-person-in-a-computer story that is set 200-300 years in the future. It's a good read but a little hard to follow at times. The story really blurs the distinction between "atomic" people (living in the physical world) and "digital" people (living in a computer). It makes the assertion that both are equally real.

It's an interesting philosophical question that takes you a different direction than stories like "The Matrix." Is there any difference between what

Cyber-themed 'Brave New World' distant future dystopia faces an existential threat.
Lots of cool and edgy ideas here.
The ending surprised me a bit as the side that I thought of as the good guys was
defeated, at least temporarily.
Excellent read.

Brilliant hard-AI scfi. Ballantyne does exceptionally well in dealing with the potentialities of replicable mind-simulations, both negative and positive. The literal deus ex machina limits the, otherwise uncontrollably vast, examination of consciousness emulation and provides an enjoyable plot framework. An important book.
Feb 10, 2016 Paul rated it really liked it  ·  review of another edition
Second book by Ballantyne in same universe as Recursion. More about intelligence and AI than about nanotechnology. More linear than Recursion although for much of the book does have two seperate timelines with Judy and Helen and Justinian Sibellius. About Schroedinger boxes and alien plants as well as questioning the benevolence of the Watcher and how humanity has been shaped.

Shelves: sci-fi, surreal
I enjoyed this book for its backstory. The characters were odd and didn't really engage me, nor did the front stage story. But the imagination of the world, the rich details, the new spinning of sci-fi, oriental, and organic elements sucked me in. I feel compelled to give it a high rating solely because it was so enjoyable from an aesthetic and emotional perspective.
Aug 08, 2008 Brendan rated it did not like it
Reading the description for this book made me really excited for it, but I just got disappointed when I actually read it. Despite the high level of technology it's very soft sci-fi and while there are some cool ideas they are not explored enough. The story was totally lacking and I didn't really get attached to any of the characters. In short, not my thing.

I did not enjoy the first 100 pages of this book, which is my cutoff for how long I give a book to engage my interest before I put it in the used bookstore pile. Life, as they say, is too short to read bad books.

Not sure I understood this book any more than the one ("Recursion") than came before it. Hard to follow the plot and how the story lines support one another, but I do find the author's ideas interesting.

A good sequel continuing in the same universe. I'm only 70 pages in, but it is expanding the old thought-provoking ideas of the previous novel while adding new ones.
Sep 06, 2010 Gerry rated it really liked it
A really solid sequel to Recursion that I felt built on the themes of free will, God, and the definition of life. A pretty good sci-fi series I will re-read.

I am honestly not sure what I think of this book. I wonder if the story would make more sense if I read the other books in the trilogy...
