"It is very easy to point fingers at 'the big bad publisher' when a story like The Smoking Gun’s makes the rounds, but without knowing the intricacies of the book business, I’d be cautious about placing blame and think about the broken promises made by authors signing contracts which they do not fulfill."
As a literary agency intern, I get to read contracts, and I've learned a lot about the business side of publishing. And that's the thing: publishing is a creative industry, but it's also a business, and at the end of the day, authors enter into contracts with publishers which are often fiercely negotiated, and just as authors expect publishers to hold up their end of the deal, authors must do the same.
I encourage everyone to write, but I firmly believe that not everyone that tries to will or should be published. And even of those that are, not all of them will be wildly successful. Many published authors have a day job. To be a published author in this day and age, requires a certain kind of personality. They have to be willing to have an internet presence, to do interviews and book tours, and above all, to work hard. You must deliver the goods/services (the novel) that you have legally agreed to provide on the date agreed upon.
