I was expecting to hate this book. I forced myself to try it because people had gone on about it so much, but I really didn't like the descriptions I'd heard: 500-plus pages, visions of a dystopian future, a fractured timescale with six loosely-linked narratives each nested within the previous one, and so on and so on. It just reeked to me of a self-regarding author determined to show the judging panels of literary prizes how terribly clever he was, and with no interest whatsoever in whether anyone normal would actually be able to read the thing.
Well, I was completely wrong. I thought it was absolutely terrific. Interesting, thoughtful, readable and - most surprisingly of all - page-turningly suspenseful and exciting quite a lot of the time. I thought it had a lot of thoughtful and thought-provoking things to say about exploitation and the abuse of power, and about the possible consequences of both humanity and inhumanity. The different voices are really well done, with the historic and present-day(ish) ones sounding absolutely authentic and the future ones chillingly believable both in the language they use and what they say with it. The stories are involving, occasionally humorous, sometimes sad and sometimes extremely touching. For example, the few paragraphs when a character in a train passes some of the places of his youth and sees them much changed are really affecting, I thought, even though the character himself is thoroughly odious.
I doubt whether many people, if any, will read this review among the hundreds of others here, but if you do I would urge you to try the book. Plainly quite a few other reviewers hated the book and did find it as terrible as I expected to. You may hate it too, but you won't have lost much. On the other hand, you may be surprised to find it as enjoyable and rewarding as I did. It's worth the risk - if you do find it's for you, you'll never forget it.
