SilenceEtchedOnAWall finished reading Hortensia, or, The Distressed Wife by Elizabeth Bonhote
Finished this. Lays it on a bit thick but satisfying ending, I had fun.
Picked The History of Lady Julia Mandeville by Frances Brooke as an influence for this, Bonhote mentions a 'Brooke' as good reading in her Parental Monitor, gonna guess Frances was meant.
