The Horror Writers Association will be running a whole bunch of special stuff on their blog during the month of October in celebration of Halloween. http://www.horror.org/blog/
They're even going to have giveaways of free stuff. Folks should check it often during October cause it should be worth your while. There's a link on this blog to that blog down lower on this page. Anyone can get there from here.
Also in celebration of Halloween, as I've previously mentioned, I'll be reading ghost stories along with five other Colorado writers on October 27th in Denver.
