I thought this book was incredible and definately worthy of the Booker. Many of my friends feel the same and we have had long debates about our various 'theories'. In saying that I currently have a friend who just cant get through it - yes it seems a bit pointless at times, even a bit ridiculous ( a tiger in a boat !)but people if you dont get to the end you miss the WHOLE POINT ! It has a brilliant 'oh my god''moment' right in the last few pages - so seldomly found(successfully) in many novels. Very clever - thought provoking, you may need to go right back to the beginnning. To those who didnt like it I would guarantee you DIDNT FINISH IT! 

Question: How is writing style?
Answer: yes it seems a bit pointless at times
