First of all, congrats! Your interest in doing National Novel Writing Month shows an excitement for writing and storytelling and a willingness to rise to the challenge of writing a whole book in a month!
I haven’t attempted NaNo in three years, but I’ll be doing it with you this year! My NaNo project is the third book in a current series, and I look forward to trying the challenge again, especially after all that I’ve learned as a writer and NaNo-er!
