Victoire la Rouge | 
A novel by Georges de Peyrebrune, a half-forgotten 19th-century female author with a male pseudonym. Free on wikisource. I read it because of its pro-working-class, proto-feminist leanings and because it is set in #Dordogne, which is the French département I'll be exploring in books this year. It is a page-turner and I really felt for the main character, a strong but dim girl raised in an orphanage without love or the skills to face the world.
Warning for fatphobia in the first chapters, and abuse
