The book is officially available for purchase (Huzzah!), though only in ebook format so far. The physical copies should take another couple weeks. And while there is currently just the direct purchase option, I'll soon have links to Amazon, Barnes&Noble, and other big names.
Of course, if you absolutely must have a paper book NowNowNow, and you can provide a mailing address, I'll happily mail you one from my stock of advance author copies. I'll even sign it for you. Because we're buddies like that. This is the first printing, and a historic event! Available while supplies last. (The contact link is at the top right.)
