I enjoyed this book, but it didn't engross me the way some books can (and do).
I've tried not to read the other reviews first, but my eyes did fall upon one complaining about Charlotte being an absent mother. Having been a single mother in my teens back in the early 70s, I can kind of sympathise with Charlotte. Although she yearns for the person she used to be, I can remember yearning to find out who I was meant to be. In fact that was what I enjoyed most about the book: its description of that dichotomy between how much you love your child - and how much you wish you could be free to be you. I can understand how some women would find that difficult to grasp, but then we're lucky enough to have this children at the right time in their lives, and with the right partner in life. I was not, though I was a little surprised that Charlotte felt the same way, as I thought she did love Henry.
I also felt that he loved her, in spite of his selfish behaviour. It was clear that they didn't communicate enough, and I wasn't sure if I was meant to take that as a symptom of their relationship or of the times.
Most of all, I felt cheated at the end. I know it's the modern fashion to allow the reader to choose their own ending (did she go back in, or did she leave again?) but to me that's a bit of a cop out on the part of the author - I want the author to tell me the whole story, and not leave me to decide (unless it's the ending of The Sopranos - that was superb, though I did shout at the telly for about 10 mins saying it wasn't allowed ).
