No need to wait. You can buy the book right now, as it’s being published in Manning’s Early Access Program. You get it in epub, mobi and pdf formats, with updates as new chapters are written. And the hard copy when it’s done, if you signed up for it. (I settled for just the ebook myself, as I have been drowning in physical books for years now.)
