Long time, no see. So I'm still in the process of writing a rough draft/first draft. It is now 75k, though I have been slacking off lately. I have a scene where a man is telling a girl a story that is central to the plot. Right now, it is over twenty-five pages (about 8k), and I'm not finished. How long (or short) should a story within a story be? I feel like at this point, this book has so much material and plot that it needs to be cut in half. I feel as though I am rushing through it, the characters and setting are underdeveloped, but I don't wish to sacrifice the plot either. Any advice?
