Why Indies are Working Together
Success in self-publishing requires a quick response to trends, robust marketing, and frequent releases. Co-authoring makes it possible while avoiding burnout. Whether you’re a bestselling author with a large back list or a debut author, readers want more books.
That’s why many authors are working together. As a co-author, you can co-write a book. Or, you can share the same universe with other writers. Writing anthologies and boxsets is becoming more and more popular.
