Make your Sample Work
When someone downloads a sample of your novel, they only get the first few pages. This is the opportunity to snare them. Whilst the intro maybe cute to you, it ain't your novel. It's great to thank Great Aunt Myrtle for inspiring your love of writing by reading to you while she changed your nappy, and your Boyf/GirlF and God and all the rest, BUT it's boring to a reader. The exciting thing is the novel.
It may be better to ship all of that stuff out to the end of the book, that way when someone gets a sample you can get them quickly into the novel and hopefully hooked into buying it. I tried to get CONSUMPTION: A NOVEL up and running straight away
