Fascinating premise, well executed! Trigger warning for just about everything, though -- this is NOT a series that shies away from having terrible things happen to its characters onscreen. A very interesting read, but only if you're up for that.
Unfortunately, the translation is very clunky, full of thees and thous written by someone with a tin ear for archaic English, and no difference whatsoever between the speech of Edo samurai and Kyoto nobles, even when the text tells us they're speaking very differently. The fact that I enjoyed it as much as I did despite the translation is a testament to the quality of the original, but it's a pity it didn't get a defter translation into English.
