You know, I could see this being the start of a pretty neat series.
The angsty story of the former maid, set a few months after this one, as she tries to keep herself and her brother alive in a country beset by all the turmoil revolution brings (quarreling revolutionary factions, hostile neighbors looking to uphold the ancien regime or fulfill their own ambitions, widespread crime and poverty), all while struggling to cope with her grief over betraying someone dear to her. Then a new girl walks into her life, and the maid starts to feel things she hasn’t in a long time.
Bonus points if the new girl is somehow involved in the politics of the new country (maybe a revolutionary or minor noble who somehow survived the purge), so the story can cut between romance a political intrigue.
