I'm supposed to start grad school next year but am taking a year off to work on my novel. I'm in my 3rd serious revision. Besides a few magazine articles, I have not been published. I know how the process works: query letters, agent, publisher. What I'm looking for is advice during the process, how to make a query letter look as good as possible. What can give me a leg up etc. Also, have any of you been through the agent or publication process? How many agents did you query before finding yours(if applicable). I would love to hear experiences, regardless of the outcome.
