This is going to be very vague, as I read an extract of this book last year and can't remember anything about it except I thought it looked good for my teenage DD to read at some point. By the power of Mumsnet?
I think it was a memoire, relatively recent, by a young woman who had perhaps recovered from an eating disorder, and had spent a lot of time seeing her body as an object, on a screen, rather than an aspect of her own self to be cherished.
That's all I can remember.! Can anyone make any guesses?!
