I've been planning on making a comeback with my web serial, and in the meantime I've done a tie-in novel that I'm going to e-publish on Amazon kindle. I've never done anything like this before and only have a vague idea about it, though. I've looked online for help, but the information I find is often contradictory. As some of the people here have done this before, I was hoping someone could give me some pointers?
Specifically, how should I format my novel? Margins, fonts, etc? I've heard that I should save it as a html before I upload it to KDP, is that correct? Also, what size should I make the cover art/image? I can't find a definite answer anywhere, but I've heard that Amazon's suggestion is outright wrong and doesn't show up very well.
Any help would be greatly appreciated.
