What this business is
You write (or commission) books, design covers and interiors, publish on KDP, and market them. Many publishers build series and catalogues in a niche rather than relying on one book.
- Fiction series (romance, thriller, fantasy and more).
- Non-fiction guides and how-to books.
- Low-content books: journals, planners, logbooks, puzzle books.
- Children's books.
- Audiobooks (through other services) from the same titles.
