I'm a librarian who loves anime, manga, and reading a wide variety of genres.
This is an excellent adaptation overall, although it didn't magically cure my dislike of some of the aspects of the original.
I'm essentially finished - these last few pages are background notes about the author, the book, and what being a governess was like, as well as a note from Crystal S. Chan about some choices she made when adapting the work. I especially like Chan's comments - she talks about slight changes she made to improve the pacing of the manga (borrowing dialogue from a later chapter of the book to make the manga flow better, for example), as well as a few of her and SunNeko Lee's fun little touches (Chan worked cats in whenever the original novel gave her the opportunity to do so, knowing that Lee liked drawing them, and Lee used Chan and her husband as inspiration for a couple details in Jane and Rochester's character designs).
