No, we haven't lost our minds and started spouting gibberish. That stands for "National Novel Writing Month Young Writers' Program," which is an initiative to get teens to write an entire novel during the month of November! No, they haven't lost their minds either--it's possible, and the website gives you the help you need to do it! You can sign up and get prompts, advice, and resources, and keep track of your word count on their website to help you meet your goal.
and click on "How does it work...for young writers?" to register and get started on YOUR novel!
