So apparently this is a hugely controversial addition to the Booker longlist, and some people are very upset it was included.

I think it's one of the best books I've read this year. I expected it to be a sort of Tom Perrotta/Jodi Picoult mashup, but it isn't like that at all. It's character-driven and really very well-written. I particularly liked the Manolis chapter, which I found wistful and bittersweet. Very well worth reading if you have time for a 480-page book.
