"The City at the End of Time" by Greg Bear

I think this was a good book but I am not entirely sure. You see I didn't really understand what was going on and now having finished it I am still not sure I understand. I got the main gist, I think, something about the end of time and the universe being consumed by chaos and time travelling dreamers who somehow link those end of days to the present day and books being some kind of bulwark against chaos. All very confusing but quite compelling reading I must admit. The story grabbed me in its own fashion and I was just hoping that I would figure it all out by the end. Didn't happen sadly. I must google for an explanation.
