Okay, I ordered the book via Amazon and have now finished it. It's an easier read than the original TL because much of the material has been condensed into something more compact. The individual anecdotes, in particular, have been left out altogether, leaving only the bona fide historical narrative. There are a few shout-outs to OTL which from our perspective might seem gratuitous, but that non-alternate historians will probably appreciate.
I hope the English translation will soon get published as well.
