This was quite the book: conceptually intriguing enough to hang with it through the complex plot structure and difficult ideas. In my mind, the book is about the nature of personhood: how our past shapes us, and how our present circumstances alter us. This is explored through the characters of Cohen, a massive AI character who "dies" by being splintered into smaller, sometimes sentient, fragments; and Catherine/Caitlyn, who "scattercasts," i.e., travels through space by having her information br...

First half of the book was very enjoyable, but the tempo and lack of interesting ideas soon became very noticeable. Also a bit confusing that there were 2 Li characters that somehow had totally different personalities. Didn't like the ending either.

Catherine Li is married to the centuries old and incredibly wealthy AI named Cohen. Not many people understand their relationship... even they don't understand it very well. But when Cohen dies suddenly, and the official reports say it's suicide, she can't accept it... in part, because death is complicated for AIs, as parts of them may still be alive. And, in fact, at least one significant part is alive, and trapped sharing the body of a pirate captain to serve as his ship's navigational compute...

Probably a little too complex and weird for many people's tastes but a hell of a blast for me. Lots of deep musings on the nature of identity and consciousness and the strange consequences the quantum nature of the multiverse. Not often we get to jump between the POVs of diverging duplicates of the main character!It amused me that I had earlier had the same thoughts Caitlyn did when contemplating Nguyen's demise - a necessary evil for a dying UN?Half a star off for the silly and perfunctory happ...

Chris Moriarty's novel Ghost Spin is the conclusion of a trilogy begun in Spin State and continued in Spin Control, both of which I read years ago, before even joining Goodreads. That long gap turns out to be an easily surmountable barrier, though... while I still wouldn't recommend skipping the first two installments, Ghost Spin stands on its own much better than many series books, and it took Moriarty only a couple of chapters to get me back up to speed again.Ghost Spin reminded me powerfully

hey this was a lot of fun, defo an improvement from the second one. spoilers throughout. i really enjoyed that it was a followup to the consequences of the first in that the bose-einstein relays that knit the UN empire together are failing because the protag, Catherine Li, incidentally was involved in stopping the mining of BE material. i liked how the consequence of that is sort of a degeneration into highwaymen and piracy. and that's where it gets really really fun, because Moriarty just fucki...

SPOILERS BELOWSo this was the third of the 'Spin' trilogy. I still stand by my high recommendation of the first two, but I've got to say, I struggled with this one. The characterization was still great, and I still really was interested in the elaboration of the theme of posthumanity - in this book, the main character, through some kind of weird quantum effect, became several people who all had their own plots, which I don't think I've ever seen happen before and which she did really well - and

It has been several years since the first two "Spin" books came out. Long enough for me to forget what the heck is going on and not quite be able to catch up. Sigh.Cohen, the Jewish cyber-sybarite, has travelled to Pittsburgh to commit suicide. A Pittsburgh on another planet, not Earth's Pittsburgh. As the first book was sort of set in a Welsh coal mine *in space*, this one is a run-down blue-collar steel town. *In space.*That's kind of cool; the problem is the background, which is relentlessly

Some interesting ideas about AI intelligence, Faster than light travel, and human evolution, but a very chaotic story line.

I probably would have liked it more if I had read the 1st 2 books in the series, but picked it up at a used book store and there wasn't any indication in the copy I had that it was book 3 in a series. With that said it held it's own as a stand alone story, but there were a few points you felt there was more to the story that you were missing. The book has a little of something for everyone. Science fiction, romance, mystery, war, and even a few rags to riches stories.

A fabulous trilogy from start to finish.

Ghost Spin is a strange story with a strange story line. It is Science Fiction. It is set in the far future when an artificial intelligence named Cohen kills himself. This is unexpected. AI's don't kill themselves. I kept reading this even though it was confusing at times. There are parts or Ghosts of Cohen that appear in the story. There is Cohen's wife Catherine. In her quest to find out if Cohen really did commit suicide she ends up sending copies of herself across the galaxy. As a result we

A clever wrap up of the series, using all of the ideas going back to the first book but creating a new "spin" on them. I waited a long time for this book and I'm so glad that it finally happened. It wasn't the perfect read that the first book was, but it was a good read with a lot of interesting ideas.

This is the third in a series. I recommend to read the first two books (Spin State and Spin Control) before trying this one. This was an elegant, lyrical conclusion for the Spin Trilogy. Good sci-fi, explained well, with believable, well-developed characters. Impressive, strange and interesting story, tight and well written. The first book and the second one in the series are better, but this is great and worthy conclusion too.

As much as I do like her, I'm all right being done with Caitlyn/Catherine, but I would love another book about Cohen in his new role. Even a novella. A short story. I seem to be a sort of Cassandra of book recs, so I can never convince anyone to JUST TRY this series, but it deserves more readers.

Well, I have at last finished Ghost Spin, a book I've probably waited the longest to read of anything I've read possibly evar.It's also one of the few books that I've read within months of its publication.That said, Ghost Spin is a thoroughly complicated, complex and difficult to describe book. Like in its two precursors, there's a lot of quantum mechanic referencing and parallel universe examination in here that I didn't completely comprehend. I'm going to be toying with what all of it meant fo...

Ghost Spin is a third installment in the Cohen trilogy, about a time past Singularity, where a supercomputer named Cohen who was once a person on Earth, has become a super AI, one called an Emergent. At the start of the novel, he kills himself, saying it is the only way to save him and the insane AI Ada. The rest of the long book is taken up with his (human) wife trying to find fragments of him and reconstruct him. There are also subplots about the human war against the Syndicate, evil higher up...

Preordered Kindle edition.

This has wrecked me for two solid days. I love this book... all of these books, but I can't stop crying for what was lost. >.<

So many great thoughtsChris Moriarty finished off her Trio of books the way she started. It is so clear that this woman is a truly deep thinker and has managed to put huge Concepts into a readable form. From the first book to the last I kept finding things that would make me stop on the page put the book down and just really think about what she was saying. This is what all of the best science fiction does it leads us into the future gets us to look at our past and see where we might be going. I...
