Congratulations on completeing your first novel draft! That is a step ahead of the writers that have not finished it. I have finished mine as well, and now I am writing a query letter. After that I will send it out to agents, but hold your horses do not send your manuscripts to agents until you have edited the novel. To make it the best it can be is the difference between an accepted or rejected novel. I have several books that will be helpful after the editing is done. In the mean time I am getting a book about Self-Editing, and I will read the book and let you know whether it will help you on your editing journey or not.
That is it for now,
