I'm in the process of preparing a novel for sale through Amazon, on the Kindle. I've got a cover, a good synopsis, a blog about it and even a video to advertise it. Anyone got any bright ideas about other ways I can make it make a splash?

My situation is that I had a literary agent who helped me edit my novel into a form that he thought was highly marketable. He then sent it out to a dozen London publishers. Two were interested, but eventually turned it down as not fitting neatly into any genre. We tried various other publishers, who weren't interested. The agent then left the business, leaving me with a novel that was deemed publishable, so I'm going to try my luck on the Kindle.

Various internet sources say that most self-published Kindle novels go nowhere - I'm looking for ideas that might give me a fighting chance.

Any thoughts?
