What I have recently finished reading was "the end of an affair" by Graham Greene, I thought it was an amazing book, which took some time to get into but eventually really caught the readers attention. It is mainly about a love triangle really between a young married couple and the main character who had a affair with the wife a few years back. The book shows very deep insight into the main characters thoughts and obsessions with the young couple, quite shocking at some points but very interesting. I had to read some passages again to really understand what going on since the way it is written is slightly confusing but very descriptive and insightful so GO read it !
