Today's the day! The book is in stores! I have confirmation. My friend Ashley just emailed me pictures of herself buying the book at a Borders. I don't know which specific store she was in, but its somewhere in Virginia. I am leaving work in about a half hour, and my plan was to stop at a local comic shop and a Barnes & Noble to see if the book is shelved yet.
Wow... now I feel like an author!
And the really neat thing? Ashley went in costume as Mirax Terrik Horn. Ashley was wearing the costume when I met her at this year's DragonCon, and I just loved it. So I guess she wore it for me today.
Edit - It's the New Essential Guide to Alien Species. Sorry. Silly thing for a writer to do, I know, leaving the title out.
