Hats off for having the courage to raise this. It is not you or your book. It is the system. A hand full of people effectively decide what 'fails' and what succeeds. I am sickened by the so called 'book world.' (Even though I look like a person who should be 'winning').
I've got to admit failure.
My second book, The Progress Trap, despite having various excellent testimonials and a superb jacket and presentation from Polity Press, has failed.
Aside from the disappointment, it's interesting to reflect on why.
I'm not really sure. I thought it was a cracking book: better than my first, which attracted a lot more attention.
Maybe I gave too much attention - at the last minute - to the current moment and current politics, which distracted readers and reviewers (of which there were very few) from the main arguments.
On one level I might put it down as a lesson learned: that you need to focus on the main task rather than run after 'relevance'. The trouble is that such failure lasts. There will likely be no other books and I'll have to try and find some sort of gainful employment.
C'est la vie.
