Facebook: I have an author page here. I’m keeping my personal page, well, personal.
Goodreads: My author page is here. You can friend me and e-mail me via Goodreads if you prefer.
Blog comments: Not the best way to contact me, especially now that I have this page and various means available through which to reach out. As an FYI, I do review each comment before approving, so they won’t appear right away. That said, so long as you’re respectful, I’ll let your comments through. If yours doesn’t get in, well, chances are you weren’t being nice.
Carrier pigeon: Good luck.
