Every October the Horror Writers Association has its Halloween Haunts event. Every day at least one member is featured and posts an article, essay or story on writing or Halloween. Most write about Halloween. The neat thing about this event is that it's free. Oh, and you can win prizes, too. Many members give away stuff from books to audio books, or even signed stuff. AND it's all free. And you can enjoy some really good takes on Halloween by some of the best writers in the business.
My entry is scheduled for October 10th this year. But I hope people will view it daily. It's a good deal and it doesn't cost a thing. So, tell your friends.
