I liked this book okay. Certainly there was nothing that made me want to put it down (well, maybe the ending, but by that point I was already finished). But I also have the disappointed feeling that it was only half realised. There are so many interesting ideas and people and places, but they feel unfinished or unexplored, and as much head hopping as we do (too much, for me, which might be an unfortunate side effect of the premise) we never seem to be following the right people or the most interesting stories. The Odyssey in Space seems like the best idea ever to me (and the reason I picked this up) but it's never quite what I want it to be. Now give me a book about Calypso and Spider House, and I'll be all over that.
