Apparently this review did not actually save, which stinks because as I recall I actually wrote a good review for once. In any case, I quite enjoyed this. The basic conceit is that the Earth's rotation starts to slow, and so the days and nights get longer. The protagonist is a young teenage girl, and so we experience this change through her point of view, and it is intertwined with her own sort of normal teenage experiences. I quite enjoyed this - it was a very absorbing read.
