The final book in the Southern Reach trilogy. While not bad, the finale was not as good as the previous two entries, and it felt more like an extended epilogue than a true successor. Both of the first two books were at least partially about situations that are radically, radically different than they first appear. They both have multiple moments were the floor just drops out from under the reader. In the third book, I didn't really find that many surprises. It was more an explication and expansion of the ideas and history and lore that are sketched out in the first books. You are more familiar with what is going on, you don't really have a central character any more (instead switching between several characters that you are already somewhat familiar with, filling in their back story), and you don't really find out that much about what is happening or has happened to the world at large. The second book leaves off with the world being consumed by a metastasising infections of un-reality, so it is somewhat disappointing that you find out all of the back story for minor characters, but nothing concrete about the pending apocalypse. :)
That's not to say that Acceptance is bad, it is not; VanderMeer is both fast paced and peaceful, skillful and evocative. I enjoyed his space whales, I enjoyed making more sense out of the ripples in the sky, I enjoyed his double-walled hogs, I enjoyed his character and scenery portraits. And in all three books I enjoyed how the characters are continually bumping off each other, always in a state of moderate bafflement and irritation. Each ofthe characters seems to have their own "meta", and never really thinks about things in the same way as the other characters. It's a neat effect, and further supports this atmosphere of uncertainty and never quite having a full grasp or model of how the world works. Lowry in particular stands out as a great grotesque. So while this book lacked the lightning of the first two, it is still enjoyable and well crafted.
