Firstly, if you're looking for a short, intense read, this is the book for you. The brevity of Barnes' text is both its strong point and also its downfall - the ending was just too abrupt for me. I do like an ending which challenges me and forces me to question events that have happened earlier, but I found this book's ending to be vague and annoying. Maybe the title 'The Sense of an Ending' is exactly what the reader gets!
The book does have a lot of stuff to enjoy. The character of Veronica is one of the best I've read in the past few years - she's enigmatic, interesting and never fails to surprise. I also liked the themes about memories and corroboration; I agree with Barnes' view that we sometimes remember events differently from how they actually were.
My favourite aspect of the book was the language. The speech between Tony and his mates, especially at school, felt very real, and the sort of talk you would hear in everyday life. There's also a lot of humour in the beginning, which helps break up the dark subject matter.
The only thing that lets 'The Sense of an Ending' down is the ending ...
