Recently, I have become quite interested in the idea of self-publishing a novel on Kindle. However, I tend to write YA novels, mainly aimed at boys, and I'm not sure this is the best market for an ebook. I don't know of any boys under the age of 18 who own a kindle or any other kind of ebook reader. What are your opinions? If I'm looking to publish on kindle should I target a different audience, probably an older one?
