The book is a concise, philosophical investigation into the unreliable nature of memory and the "stories" people tell themselves to maintain a comfortable self-image. 'The Sense of an Ending' by Julian Barnes (Review)

The Sense of an Ending is most famously known as a Man Booker Prize-winning novella by Julian Barnes (2011) and was later adapted into a 2017 film starring Jim Broadbent and Charlotte Rampling. Both versions explore how memory acts as a tool for self-deception rather than a record of facts.
