This is not my usual genre, but I picked it up in a charity shop for some diversity and as a light read. I would say it's thoroughly average. Average plot; predictable but with some minor twists that were mildly interesting. Average character; a little bit more fleshed out than a sterotype. Average character development; even though Susan the protagonist learns a lot, it seemed subconscious and passive rather than active and acknowledged. I didn't particuarly like the inference that Susan's development was for the better when it was clearly evidenced that she was happy as herself before too.
