I'm hosting a week of character interviews on my blog, the Vallory V Blog, from September 10th -15th for romance writers of sweet to sensual to erotic. Please contact me if you'd like the Friday or Saturday slot. My idea is to include book covers and buy links on the sidebar to my blog from September 1st through September 15th and run the interviews from the 10th -15th. It should be a great opportunity for added free exposure for your book.
Character interviews are also an additional source of marketing aside from the usual author interviews for self-publishing authors. Let me know if you are interested at firstname.lastname@example.org
