I read anything that's nailed down, or even just moving slowly. Cereal boxes, candy wrappers, all genres, etc., and I don't always have much time for arbitrary distinctions like literary fiction vs. genre fiction.
(not Eleven, Twelve--the one where they rob an Italian museum of a Faberge egg and leave a replica in its place).
So, if you've read the other Glamourist History books, you know what to expect re: Regency language, mores, manners, etc. But what this one adds are large streaks of humor and hijinks. It's not ALL fun and games for Jane and Vincent, not by a long shot, but they'll get by somehow and get even if they can. Other strengths include the excellent sense of place (the island of Murano and Venice itself), Lord Byron's(!) characterization, and the more complex plotting, which MRK pulls off most satisfyingly.
Weaknesses: The title--I understand wanting to continue the Austen feel, but it really has nothing to do with the events of the book. Also, Jane's characterization felt a bit off in places--specifically, her continuing and unnecessary guilt about something major that happened in the last book (no spoilers!). It just seems like Jane would have come to terms with it by now, instead of being triggered so often. But this is minor.
I plan to keep reading the books as long as MRK keeps writing them...they just keep getting better.
