Interesting. I have at least three unpublished books... I have never figured out the key to getting published. I post them on the web and they seem to do fairly well.
It's because you're honest and a man of integrity. I'm not saying Wilcock isn't interesting, and he has hooks that draw you in. I commented because he uses a style I recognize. I'll spend some time and come up with an example im more depth of what I'm trying to say - not picking on him so much as the genre. Always big promises with the carrot just over the horizon.
I think it's VERY interesting that you have 3 unpublished books. I'll have to check that out. ;)
