This is a charming Regency romance framed around the "woman presents as man in order to do things prohibited to women" device. In her case, she's impersonating a specific man after his death, so she and her female relations won't be turned out by his heir. I normally dislike this kind of device, but it's pretty fun here. Mostly this is because Millicent is hoot: she decides she's never going to pass as a fashionable or ideal man, so she sets her persona as a rattle: unserious, continually bantering and joking and being ridiculous. She is utterly delightful. Her male love interest, Shoffer, does not deserve her. The first 2/3rds of the book are wonderful, with most of the action dealing with various social problems, most unrelated to her ruse. Most of them are lighthearted and all are resolved by wit.
The last third is somewhat marred by the romance part kicking in. Shoffer's treatment of Millicent-as-woman is just ... meh. He feels typically misogynistic towards her, and it's in keeping with the period but not nearly as fun or appealing as his treatment of her when he thought she was a man. He improves before the end, but still.
Even so, there's a lot of fun stuff in the last part of the book, so well-worth reading. This was totally going to be a 9, but I'm downgrading it to 8 for wobbling on the ending. Nonetheless, had a good time, well worth reading.
Also, I kinda want to write a trans man story using the same kind of framing, but I'm not sure I have the patience to write in a trans-hostile, misogynistic setting for long enough to do so. -_-
