Okay, to start: not every book is for everyone and everyone is entitled to opinions. My opinion is that it is okayish. I liked the second one more (Dark Forest).

That said, the book is weird. It's like going to an art gallery and staring at paintings. Each painting is a chapter. Everything is beautifully depicted but totally static. The chapters in the book are look someone describing a painting to someone in the gallery who is blind.

And the paintings (and their descriptions) are good, but they aren't mind blowing or anything.

But, if you sit an digest it for a bit afterwards -- continuing the metaphor: you're on the train home from the gallery and it hits you -- there's themes woven between them. In my opinion, it's actually better once you step back and look at the whole book as though it was an exhibit of paintings with a theme. A few days removed from the book, you'll be returning to the ideas in it, even if all the characters and plot points blend together.

Anyway, my two protons.
