NaNoWriMo. I've participated every year since 2005. I've never 'won' by writing the requisite 50,000 words, but November is always my most productive month now.
Usually, NNWM just ups my word count on whatever my current WIP is, but this year I will be starting a new novel with the 'regular' participants. How is it different? Glad you asked. Okay, maybe you didn't ask. This novel is a collaborative effort. I'm writing in conjunction with my wife, Gwen Mayo.
During NNWM, Gwen will be finishing up the sequel to Circle of Dishonor while I start work on the joint novel. We've been doing research on locations and history for the last month (you can read more about that here). It will be a mystery novel, and will be set in Florida. Our heroes aren't characters from either of our novels, but we've written a couple of short stories with them and one tale, at least, has been accepted for a 2013 anthology.
In other news: I will be featuring at least one author interview in the near future, plus, I hope, more frequent posting. This has been a long, difficult year for me. 2011 was one of the best years in my life; 2012 has been one of the worst.
