I finished Engine Summer. Beautiful. There was something incredibly melancholic about the post-apocalyptic world, the loss of the angels' world combined with the loss of love and self, and I really enjoyed the mythical or mysterious proportions certain people or even the most mundane inventions of the past achieved. I think I guessed halfway through the final revelation and then spent the rest of the book dreading it would actually happen and it still hurt. The Boots thing though. There's a sort of understated horror there, as much or perhaps even more than the ending and it becomes quite obvious in retrospect. It made me feel bad especially for Rush and what he did to be what he thought Once a Day wanted. There's actually a lot to say, from the theme of stories to the idealisation of the past, good and bad things included, to love and miscommunication to trying to find a sense in relics from the past and so on. Just really good.
