I will start by saying I enjoyed the twist at the end.

However I must say I spent most of the novel irritated by the scenario author Paula was playing out for the main characters husband and wife Leon and Jane. Considering that I am someone who is highly lead by emotions I was very surprised that I did not emphasize with either of the two main characters at all. I just did not connect with them.

In summary, It's a good quick read, ideal for your summer holidays.
