Well, okay, I liked it, but I'll be really mean and say that I'd never recommend it. I liked it because there was so much wrong with it that reading it felt really good. I know I'm not making any sense.
I despise the bakumatsu period because it's so popular that it has become a collection of cheap plot devices... and this book is a testament to this. Basically it consists of taking a handful of historical personalities (Takasugi Shinsaku, Katsura Kogorō, Yoshida Shōin, that sort) and sticking them into the monotonous dough of the story in hopes of giving it some weight, because the story in itself is just one of those paint-by-numbers compositions about a Strong Woman Who Is Ahead Of Her Miserable Yet Picturesque Times. The historical guys fail to help though, because they're completely lifeless. They are just hopping about, popping in different places from Nagasaki to Kyoto, and showing unmotivated interest in O Tsuru (the heroine) who wants to be a doctor. O Tsuru whines about being an ignored woman, but truth be told I couldn't see why, because all the guys constantly noticed her whether she was in disguise or not. Cry me a river miss. Of course it was written for a noble cause and all that but come on, this is not the way to go. Omg I sound like I'm drunk. I'm not.
Well, there was something about a forbidden love on the cover. I found one scene I liked, O Tsuru's meeting with the geisha O Ume, and thought whoa, cool, but no... the forbidden love was of a less forbidden sort. Pity. Oh well. I think that historical novelists in general lack the stones to write an entertaining slashy story. They always put slash somewhere in the background and hope to score some points. Lame. (That's why I like Laura Joh Rowling.) Wow that's a whole lot of digressing. Okay. But seriously, what was with those "geisha houses" where the men went? Judging from the description, the author meant just brothels. It was confusing for me, and probably misleading for other readers. Otherwise the research is pretty good as far as I can tell.
There was a lot of untranslated Japanese and buckets, buckets of proper names. And the characters talked like that: "As you know Bob, the shogunate is bad and needs overthrowing big time." I'm serious. That's why I read this book.
