Every November is National Novel Writing month in which writers participate in writing a 50,000 word novel in thirty days.
The idea was started in 1999 in San Francisco by Chris Baty [Facebook]. Every year since then the event has grown from 21 writers to over 300,000 in 90 countries.
The center for the activity is the NANOWRIMO web site. There are also various local chapters of the site including one in Flagstaff. There is a little over two-weeks to sign up for the event.
Participants sign up on the NANOWRIMO web site and agree to write a certain amount of words a day totaling 50,000 by the end of the month. The web site also allows authors to communicate with one another and provide encouragement.
The organization does not guarantee a novel sale, of course, and it will probably need a re-write. The web site only encourages the process after which you may have a novel to submit. Or you might choose to self-publish through web sites such as LULU or CreateSpace.
