Apparently not on the Russian store, according to a fellow ACT. But there is a Kindle version coming out soon, too.
Now that I've read it cover to cover, be aware, this is not a "how to use FCPX" book. This covers the discoveries and workflow schemes of the post-production team who edited Focus. Lots of film jargon, lots of technical information. If you're not familiar with feature film post terminology, you could get lost. But it is really great information, and will be a huge help to many folks wanting to implement FCPX into a large post workflow. Super good read, highly recommended for those interested in this aspect of using FCPX.
