I am rewriting a novel from several years ago, to submit to an agent. I did a severe trimming job and now am adding new material. My problem is that I tend to be a sparse writer. I now have 50,000 words and am fairly close to the end. Of course, I can go back and add more material. My question is, how long must it be, roughly? It is paranromal fiction. Would 70,000 words be okay? Thanks.
