The first step to marketing a book is to publish a great book. And to publish a great book, you need to write a great book.Once you’ve organized, written, and titled a great book, then publish it using Amazon Kindle for ebooks (and printed books now) and IngramSpark (for printed books to be sold via bookstores).
For details on doing this, see How Do I Get My Books Published?
Then use the 200+ book promotion sites and author promotion sites (and Facebook groups) to promote your book: 223 Ebook Listing and Book Review Websites.
Those should be your first two steps.
