A Lady for a Duke
by Alexis Hall
Wholesome without crossing the line into unbearably twee, which is not easy for my jaded tastes, so call this a win. Pulls off the balancing act between the existence of social trans- and homophobia without making it a plot point, though it wasn't always graceful---I was always very aware of what Hall was aiming for, and that it wasn't easy work. The book's not interested in historical ways that people identified, these are very much people with 2010s and '20s cultural understandings of sexuality and gender who happen to be shifted into the past.
It got a little silly in the last act, where all of a sudden there are a lot of casually queer characters, but at least there was finally more action than angst.
