When I picked this book off the shelf in my local charity shop I thought it looked familiar. Then I read the blurb and it sounded like a storyline I recognised, but I still wasn’t sure if I’d read it before. Since it was only £1, I took it home and read it in the bath.
It turned out I had read it before, but I didn’t notice until quite far into the book, so it must have been a long time ago. And it didn’t matter that I’d read it already, because it was very good.
