Man Booker finalists' sales figures

I had a bit of a shock reading the UK sales figures, quoted by Mark Sanderson in his Literary Life column in the Telegraph, for this year's six Man Booker finalists. Only Ian McEwan's slim volume On Chesil Beach appears to be doing fairly well (according to Nielsen BookScan August 18^th figures) with 110, 615 copies sold. The sales of the much-praised Mohsin Hamid's The Reluctant Fundamentalist stood at 2918 copies and Lloyd Jones' Mister Pip, close behind,  at 2802 copies. (We presume that they were all in hardback. But you will get the perspective when you consider that, considering purchasing power parity, the hardback in UK costs half of what a paperback costs locally.) In fact the five finalists' combined sales, besides Ian McEwan's, comes to 10,155 copies sold.

And this happened after the announcement of the long list. The sales figures in April were: Ian McEwan, 99,660 copies. Mohsin Hamid, 1519 copies. Lloyd Jones, 880 copies.

So what gives? Of the six short-listed books I have only read On Chesil Beach. While it is competently written and does have its moments, which is the least I would expect from an author like Ian McEwan, I am afraid I was not terribly excited by it. In fact, I don't even know if I would call it a novel. It is part of a much longer story perhaps, like a starter with no main course and no desert -- and I am not a very happy person when they overdo the lettuce in the salads, anyway. (Don't get me wrong; I will be taking quite a few sentences from that book and calling them my own.)

Do we really have a really bad crop this year? Have writers and publishers completely lost the plot? Or is it the end of the world?
