Here's a suggestion:
Do you know anyone at a major newspaper? Prominent online journalist? Booking agent for a genre-related convention or gathering? Use that connection to get an interview or highlight moment set up. Make sure the moment won't be wasted: Discuss before-hand what will happen, what you want to happen (ie, create some promotion for your book, website, etc), anything you want to discuss.
You might need to create a "press-kit" to send to them, especially if they have to answer to someone else about why they booked you. And, of course, if it works, be as prepared and professional as possible; make yourself look good.
That exposure can be a great kicking-off point for promoting yourself and your work. If it works, you might be able to move up in that promotional area, to bigger papers, gatherings, appearances.
