What is a Book Manager? I googled the term for the first time and couldn't find a real job by that name. Publicist, yes. Social Media Manager, yes. Book Agent, yes. But not a Book Manager.
However, I'm a book manager. I don't call myself a publicist or a social media manager --- I'm both and so much more. When I started managing authors' books, it sounded like the perfect title, so that's what I called myself.
In this day and age, authors -- especially indie, hybrid and self published -- have a lot of things on their plate, and most of them don't know where to start, what to do, and how to do it in a way that produces results. They spend so much time on social media, paying for marketing services, hiring editors, cover designers, formatters, or doing these things themselves, and many still don't sell enough copies of their books. Wasted time, wasted money, no results.

That's where I come in. I do all the things an author needs to do, except write. And that's the awesome part about having a book manager. My clients can now focus on what they love to do best, and that's write. As a book manager, I guide the authors on what they need to spend time on to further their careers, and what's only a waste of their time and money. They don't become victims of scams or sharks circling the industry. Except for book development, the only thing they need to spend on is me. I guess the best way to describe it is... it's like having a publishing genie in a magic lamp at your beck and call. Just rub the lamp whenever you need something and you can have it... for free or at a very discounted rate. The authors I manage have the publishing strength of my author services business, The Book Khaleesi, behind them. How many can claim that? I'm proud of that fact because I know that's very rare. Even independent publishing houses outsource the development of most of the books they handle... to the lowest bidder.
What's the value? Do my clients' books get edited for free? No. Do their books get formatted for free? The new ones, no. Do I design their covers for free? The new ones, no. But if I feel that I need to update the covers or the manuscripts of the books I handle, I do. For free. If the book is not selling... for example, I might decide to change the cover. That's free.
