Are You Writing to Market?

If you're not planning on writing to market, then really anything is fair game. Don't be surprised if your series struggles a little bit or if you as an author struggle a little bit to find where it really fits in the market. By studying what is selling and what other authors are currently doing, you can get great flashes of insight into what might also be coming next. That in turn can help you get a leg up on a trend even before it comes.
