As an indie author you are also a publisher. You are concerned not only with the content, but the look of the book. One of the most important things to consider is formatting and layout of the interior. It has to look professional.
One great way to do that is to learn to typeset using a real typesetting program. A great pram for that is Scribus.
This multi-video series shows you in detail how to use Scribus to typeset your novel, from beginning to end. The best part is, Scribus is FREE, and so are these videos.
Scribus is not a word processor.
I uploaded and attempted to use Scribus several times before I decided to buckle down and learn it. It's not intuitive, but it's quite powerful.
These videos will show you step-by-step how to use Scribus to typeset your novel.
And did I mention that they're free?
