A relatively short Regency novella, with a f/f match that’s a spin-off from an existing m/f series. It’s lovely to see more entries into the f/f Regency field. (Pro tip: there are other ways to make your Regency heroine stand out as non-conforming than to give her scientific interests. I mean, I’m all about the geek girls but it feels like it’s being treated as obligatory.) The story is well-written with engaging characters, though either it was relying on the reader being familiar with the prior books, or it was trying to stuff too many side characters into too few words, because I felt like we were getting the synopsis of several novels’ worth of plot. If, like me, you’re pining for more f/f romances in traditionally popular historic settings, this will be a treat.
(I have a vague recollection of having other, more detailed thoughts about this book, but that's the problem with writing reviews long after finishing.)
