I write a lot about knowing the market for your book which sounds so much more technical than it is. Knowing your market simply means knowing the readership and genre that best fits your book. Is it fiction or nonfiction? Believe it or not, that can actually be an issue. Is your book SFF or romance? While it might have both in the book, it cannot be both genres. They are two different sections of the bookstore. So is it SFF with a romance in it or is it paranormal or SF romance?
If you’re unsure of the market for your book you need to be reading. Who would you compare your style and writing to and where is that person shelved in the bookstore? How is that author categorized?
If you are absolutely determined to believe that your book is a little bit of everything you might seriously want to reconsider your book. Readers tend to be genre specific. They read and look for romance or mystery or SFF or literary fiction or nonfiction. Few readers are out there searching for a book that’s a little bit of everything.
