This would be better classified as a short story/novella. I read it in a little over an hour. Granted the story is technically well-crafted and well-written, it's not a good book. It reminded me of an essay you had to read about a "morality story" example in an old literature book. The two central characters were pretentious, self-absorbed, and unrelateable. You don't feel bad for them at the end. The pages kept turning, but perhaps it was because I was dying to know what was going to happen... surely a Booker Prize winning book had to have some kind of satisfying ending? It had a satisfying ending plot-wise, but I walked away with very little. As another reviewer said, this should have been in a literary anthology or lit magazine, it doesn't hold up as it's own.
