Spoiler review. 
I found this book very frustrating. How a solicitor couldn’t see the life she was living and would blame herself for being a bad mother. Yes, she did wrong by cheating. But she was in a loveless marriage where her husband constantly belittled her! I was glad at the end when we found out what he had been doing even longer than her affair, although it did make me feel sick the things he did. I was left with a weird feeling of meh after reading this book. I did like how the beginning linked with the end, however it took me few times reading it to realise what had actually happened.
