Did I like doing this? Not really. In some senses I feel it's cheating the reader, because, while the novel does split neatly into three parts, they are part of the same novel. However, there are dozens of indies out there who claim to have a 'trilogy' when each novel is barely the same length of one of these parts. I wrote Tube Riders with an eye on getting professionally published, not as a marketing ploy. However, I'm making almost no sales and I'm getting almost no exposure, when far, far worse writers are making a living. I'm no Dickens but just from what I've read of other indies I'd say with all modesty I'm easily in the top 10%. I glanced at a Look Inside section of a novel of a guy constantly whining on the KDP forums about not making any sales, and he had a simple spelling error in his first sentence. I mean, come on.
I don't want to cheat anyone, and I want to offer the best product that I can. But I really want Tube Riders (and my other novels) to sell, because, compared to so much of the other self-published stuff I've seen, they deserve to.
