I have started a blog called NaNoDoMo (National Novel Donate Month). I'm donating all profits from my horror novella UNBORN to relief efforts for Hurricane Sandy, and I'm hoping many other authors will join me.
Please stop by and leave a link to the book you would like to donate from for the month, and please spread the word. Together, we can make a real difference.
My monthly sales wouldn't buy lunch for a family of four. I sent a doncaiton to the Red Cross and have an appointment to give blood week after next.
Good luck with this.
