I'm currently reading Her Fearful Symmetry, by Audrey Niffenegger (author of The Time Traveller's wife). I have about 30(ish) pages to read and I don't think I want to finish it. I've a feeling I'm going to be disappointed......mmmmmm!
I've just read One Day by David Nicholls and I LOVED it. If you haven't already read it, put it on your Christmas list. Sad, funny and thoroughly enjoyable, I want to read it again.
