Robust, peaceful, and confident, the Commonwealth dispatched a ship to investigate the mystery of a disappearing star, only to inadvertently unleash a predatory alien species that turned on its liberators, striking hard, fast, and utterly without mercy.

The Prime are the Commonwealth's worst nightmare. Coexistence is impossible with the technologically advanced aliens, who

6.0 stars. On my list of "All Time Favorite" Novels. As has been mentioned before, this book is really the second half of a much larger book began in Pandora's Star. When counting the first book, this story comes in at almost 2000 pages. As daunting as that may seem, I was amazed by how easy it was to stay focused on the story. All of the different plot lines were so interesting and well done that I was never waiting for the pace to quicken. No doubt, Hamilton spends considerable time on details ...more

If you have read Pandora's Star previously starting on Judas Unchained should feel like coming home, as there would be no need to familiarize yourself with the settings or characters. On the other hand, if you attempt to read this book without having read Pandora's Star first it would be like wandering into somebody else's home by mistake, wondering who changed your furniture, realizing your mistake and make a quick exit before the cops arrive.

“Finally, this book is over!” That was my final thought. After an exhausting total of over 2,000 pages in this saga, I was ready for it to wrap up. I enjoyed the story overall but have a few gripes with Peter F. Hamilton.

Hamilton did an excellent job creating the Commonwealth universe. I really enjoyed the technological advancements yet it was familiar and fun. There are more toys to play with and the concept of rejuvenation is really interesting. The progression from modern day to the 24th cent

I have a love/hate relationship with Peter Hamilton's books. He's very adept at introducing interesting technology and making a faster-than-light society plausible but, as with a lot of these hard-science, libertarian SF authors, he badly needs an editor. I was skipping over multiple pages of irrelevance in both this book and its prequel, Pandora's Star. He also has far too many "main characters" who (despite 800+ pages) never seem to come alive. They all speak with essentially the same voice. A ...more

After I finished Pandora's Star , I ordered this sequel online and began it soon after it arrived at my doorstep. This is significant, because while I do not adhere religiously to the general order of my to-read list, I try to follow it in good faith. I couldn't wait over a year to read Judas Unchained, so despite my general moratorium on buying books, I made an exception. And I'm glad I did. Judas Unchained is off the frelling chain!

Book Review of Judas Unchained (Ass End of The Commonwealth Saga, by Peter F. Hamilton)

In a spirit of full disclosure, I think of myself as a rather lazy person. So it should come as a bit of a surprise to me (and you, if you know me) that I am inspired, nay, compelled to submit a review of Judas Unchained (and the Commonwealth Saga of which it is the ass-end). But it does not surprise me. In fact, I’ve been saying for weeks how much I looked forward to finishing this series just so I could get
Executive Summary: An enjoyable conclusion to the Commonwealth Duology. I plan to check out the Void trilogy at some point in the future.

Audio book: John Lee once again does a great job. He doesn't do voices, but he's got a great reading voice that I could listen to for hours and seems well suited to Space Opera. I'm excited to see he reads the Void series for Tantor as well as a few other books I plan to check out.

Longer review appearing much later than I anticipated... ah well.

This book picks up immediately after the end of Pandora's Star, and it distinctly benefits from not having to establish as much worldbuilding as its predecessor. Here, instead of introducing the reader to the numerous worlds and characters of the Commonwealth, Hamilton can simply jump right into their stories. With one major exception, the plot feels a lot tighter and less of it seems extraneous to the point. That said, the pacing

Wow! What a ride. This is Space Opera at its finest. This second book in the Commonwealth Saga can’t really be described as a sequel as much as a continuation of the same story. If you put both books together you would be unable to discern where the break between the two would be.
As such, a lot of my comments made in my review of the first book still apply

Dreaming heavens, finished at last! Fascinating read. Hamilton's science is the kind I like to read and immerse myself in: realistic with a good sprinkling of sci-fi magic here and there to keep the reader wondering. In this book there are lots of these without becoming overwhelming. The story starts where it's left off in Pandora's Star, and one surprising thing I noticed was that it pretty much moved forward with only brief reminders of what had happened in the first book (which I liked becaus ...more

Don’t approach this book as a sequel to Pandora's Star. It is merely a continuation of the story. The two books form a cohesive whole, and are really just parts one and two of the same story. There is no way, really, that the two books can be read separate from one another.

The war between the Commonwealth and the Prime was always going to reach critical mass in this novel, and this is more or less what happens. However, things didn’t pan out quite how I was expecting. In this novel there is a sl

‘Judas desencadenado’ no está a la altura de su predecesora, ‘La estrella de Pandora’. El cliffhanger con el que terminaba ésta, me hacía esperar un inicio más contundente. Pero no ha sido así. La cadencia de la narración, ya desde el principio, es excesivamente pausada y se extiende durante páginas y páginas sin que prácticamente suceda nada. Las piezas tardan excesivo tiempo en ponerse en juego y la trama se pierde en los detalles. Lo que resultaba absorbente y refrescante en el primer libro, ...more
Combined with 'Pandora's Star' this is by far the longest and most detailed space opera I have ever read. Judas Unchained is listed as the 2nd book of the Commonwealth Saga, but in reality the two books are just one very long story. There's not even a hint of a conclusion at the end of Pandora's Star, so you have to read both together. In paperback, that's 2,000 small type pages.
In terms of content, this book hit's all my particular sweet spots required for the genre. There is so much in here

You know that feeling you had in college after you finished your last final before vacation? That happy feeling of relief, of accomplishment, and of finally, FINALLY being done. Well, that’s the feeling I had after finally finishing the Commonweath Saga the other night.

Pandora’s Star and Judas Unchained should essentially be viewed as one LONG book, nearly 2000 pages long in fact. It is epic, in scope, in vision, in ideas…….and in bloat. Hamilton really does need a better editor.

This book had so many good things going for it, but a few bad things really overdone degrade the whole story.

The ideas and story are brilliant, and keep you interested. There are only 2 problems:

1. Hamilton cannot write characters with personality at all. They are just stereotypes and many of them act so similar I couldn't tell one from another. All the soldiers acted the same, all the villains acted the same, and everyone had the same attitudes concerning most subjects. I assume they are the a

One of the advantages of such a long story, and I include Hamilton’s ‘Pandoras Star’ as part of this story, is that you can revisit forgotten characters and events from the earlier pages to great dramatic effect later on. Quite a few such gems get deliberately buried in the intervening text and are delightfully resurfaced when least expected. After my second reading of this pair of novels, I now hold a greater respect for the structural planning that went into it’s plot line and pacing.

My Reaction: I could hardly contain myself to wait for the ending and find out whodunit! This book - sequel to Pandora's Star - defies genres and contains elements of science fiction, space opera and mystery.

My Synopsis: While more and more people are beginning to believe that the Guardians of Selfhood have been correct all along about the existence of the Starflyer, the Prime launch an all-out attack to take over the Commonwealth and wipe out as many humans as possible, and en

If you made it through Pandora's Star, you will definitely need to keep going with Judas Unchained. If they had tacked Chapter 1 of Judas Unchained onto the end of Pandora's Star, you wouldn't tell the difference. And in Judas Unchained, you get all the benefits of Pandora's Star without the confusing three hundred pages of introduction.

Judas Unchained continues the story of the Commonwealth as they battle against aliens both in and outside of their civilization. It basically felt like this enti

Is it good? Yes.
Is it worth ~1800 pages (including Pandora's Start)? Not sure.

The best is still the world-building: I can't remember any sci-fi that can rival it and only the best heavyweights in fantasy could beat such a complex (but feasible!) world.
Not all good, since in this second book the characters start feeling a bit flat: Everyone seems to behave the same way, just with different goals.

But the main issue of the whole endeavour is that, although everything adds together at end (which is

These two books are simply two volumes of the same novel, dubbed the Commonwealth Saga. In the tradition of the other (even more) massive Hamilton opus, Night’s Dawn, it is a somewhat daunting cornucopia characters and interweaving subplots. This author can get away with it, since even his explanatory filler is eminently enjoyable. A very rich societal backdrop forms the stage for a drama with some very unexpected twists and turns. The most insignificant details come back to haunt the characters ...more

The second book in common wealth saga Judas unchained was hit and miss for me in some ways, because many of the things which I liked in the first book became a bit redundant in the second book. I think Hamilton has spent lot of words micro managing the story in this book, due to which some of the most intense scenes in the book dragged out a lot. The story wraps out properly in this book but the whole starflyer conspiracy felt like a red herring to me due to the fact because we do not get its po ...more

I used to really like Hamilton. His Night's Dawn series, all two million words or so of it, was great when I was younger- kind of Dickens meets Asimov, with billions of characters, subplots that zip around an immense and vivid universe, alien aliens, etc.

Hamilton was one of the first of the new space opera writers from the UK but his work at both novel (and series) level and his short fiction was limited to one main universe. He branched out with the very interesting Fallen Dragon which satisfie

Incredible science fiction from the master Peter Hamilton. Book two, or really more like the second half of Pandora' States is a complex, hugely entertaining space opera that is really about an alien invasion. I loved both of these books as they appeal to my tastes and my favorite genre. I do however have some issues with them. The sheer size makes them difficult to complete and as a result to truly love. At over 2000 pages for just two books, most other authors would have written it as f

This is the concluding volume of the Commonwealth Saga. Human civilization has spread over a few hundred solar systems. Worm hole generators allow instantaneous transportation among these worlds. Space ships have been designed that can travel much faster than the speed of light.

One of the technologies that has been developed, is the ability to copy memories. By downloading memories to a memory cube, a person can be "relifed" if he dies in an accident (or is killed). Rebirth is equivalent to clon
