The publisher is now accepting advance pre-orders of the book. The link can be found at the top of the transparent power link in my first post, or directly here:
I've heard from a friend of mine that he had system trouble completing the pre-order. I'm passing that info on to the publisher, so if for some reason you are unable to complete your order hang tight.
Also, the publisher will be offering dojo discounts for multiple purchases on a case-by-case basis (contact the publisher for more on this when the book hits general release).
I'll post further updates here as I hear of them.
