I thoroughly enjoyed this book. It's a bit slow to start but then it races along in very entertaining fashion. I was also surprised and delighted with the ending because I couldn't see how she was going to finish the story satisfactorily. But she did it brilliantly and with a superb flourish!
However, I think Jo's editor needs to to sort out a couple of the glaring anomalies before it comes out in paperback. The 'coupling' takes place in the sitting room and yet later on there's a mention of it having happened in the bedroom. See also page 146 where Alice's name miraculously changes to Gina and then back again. And somehow at one point Alice is first 19 and then suddenly 18 years old. Tut, tut - it's the editor's job to spot this kind of thing! (I know I'm being pedantic but when you read the book in one sitting as I did, you tend to notice that kind of thing).
A great read, though. Well done, Jo.
