I know you're on Goodreads--are you a member of any genre-appropriate groups that allow self-promotion (most of them seem to)? I often investigate books that are promoted in my Goodreads groups as long as the authors are polite and follow the rules.

ETA: It looks like some of the links on your page are screwed up--the Amazon US link goes to Lulu, and when I hovered over the other links some of them had your site's URL stuck to the front. That might be an issue with quotation marks or something like that.
