So this is definitely exciting stuff. Well, to me, anyway.
As part of the preparation and marketing for the sequel to The Ninja Librarian (that would be Return to Skunk Corners, coming in August), I have a new cover and format for the original NL. As soon as I've had a chance to review the proof, it'll be available, as a "Second Edition," since that's the way CreateSpace works when you change the trim size. It's already on Smashwords, and if you own a copy, you can download the new one free (though the only thing that's changed is the cover, and one tiny typo I finally removed).
The new book is a more standard size (CreateSpace's claims notwithstanding, 6x9" is not the most common size!) and has a cover that I think better reflects the nature of the book. In fact. . . here's the new cover, front and back:
Wait until you see the cover for Return to Skunk Corners!
