Last night, while eating excellent mexican food at Taqueria El Rancho, I finished "Absolution Gap" by Alastair Reynolds. It was my second (or third, if you count that I just finished half of "Revelation Space" before it was destroyed by rain) Reynolds book. The whole book was very captive and the pace was incredible. From the start you follow three different settings in different parts of the universe, after half the book it merges into just two stories you follow. And in the last three high paced chapters all the loose ends tie up and you get eject into a reading frenzy that is unavoidable!
In Reynolds universe every book add to the details and it feels richer and richer all the time.
But this book is not for everyone, it's "hard" science fiction with a lot of reference to physics and space science. Reynolds has worked at ESA so he probably know more about physics than most people. His books are very careful to not break any rules of natures, even though they bend them pretty far in some cases (see the Hypometric weapons for example). The books also challenge the reader to follow at least three different story-lines.
I am looking forward to my next Reynolds book (I need to surf amazon I guess :)), in the meanwhile I will finish Gibsons "Pattern Recognition".
