There is a slow build up, a couple of unsurprising twists and then one hell of a gut punch at the end. It's no wonder people have been talking about this ending! It's slightly out of the realm of just straight thriller, there is a little tiny droplet of supernatural edge to it (nothing more extreme than lucid dreaming). Per usual I buy everything hook, line, and sinker at the book which only sets me up for the fall. But honestly, I don't mind that, not all. Louise is a single mum working as a secretary in London and she has the worst possible luck. She finally meets a man at the bar and it turns out that it is her MARRIED new boss at work. Once they get past the initial weirdness they re-start their affair but things get weird when Louise makes a new friend. Her boss's wife, Adele. It happens completely by accident, but now she finds herself dependent on both of them. However, things are not what they seem with Adele. What is going on behind those eyes of hers? Pretty good thriller, kept me entertained and guessing!
