This is one of a number of published books written by Patrick, who is a barman at my local pub, here in Bath. Despite all the well-deserved great reviews and accolades, I expect you have never heard of Patrick, or the titles of his books (the other one in Simon and Schuster is 'Blown Away'), and it was not until I saw him selling copies on a stall at the back of the pub, that I realised that he was even an author - let alone a published one. Let me know if I am wrong.
I suppose the moral of this story (the blog, not his) is that the struggle is far from over, even once you have an agent, and even after that agent has secured a couple of deals for you. It's a demoralising story, in fact.
So when people like Janna Qualman react badly to anyone voicing their opinion on the viability of a half thought-out literary project which has barely left their word processor, they ought to consider Patrick, and the many thousands of authors who are published every year to great acclaim, and never heard of again.
