There is an order system computer glitch affecting author Elizabeth Bear's new novel, Ink & Steel ISBN 978-0451462091, which is creating distribution problems and preventing the book from getting into stores. If you are looking for the book and can't find it at your local brick & mortar, please ask them to order it by ISBN (evidently it is not in the order system under byline or title.)
I've also had reports (which I've since confirmed are true) that my new StarDoc novel, Omega Games, is now being shipped by B&N.com. Which really isn't a problem except that it's being distributed two weeks ahead of the laydown date. Nevertheless, if you want to get it early, that's where to go.
