I just got the email invite to Ad Astra. This is where Julie Czerneda launched her Polaris: A Celebration of Polar Science anthology earlier this year. My story, Polar Shift, is the second story in that antho; I wrote it as Emily Mah. Her launch was the most successful one I've ever seen. We signed books for an hour and the con sold out of copies by the end of the weekend.
Me, I was still getting used to having booksellers ask me to write in their merchandise. I don't know that I'll ever get used to taking a pen to the half title page of a published book.
We probably won't be able to make it all the way back to Toronto next year. I'll think about it and count pennies. It's tempting.
