I'll share some of the children's and young adult series that I've collected over the years. All of these are pretty long series from French authors.
The Classics:
Les six compagnons - Paul-Jacques Bonzon
Fantômette - georges chaulet
Sans atout - Boileau-Narcejac
Langelot - Vladimir volkoff, aka Lieutenant X
Michel - Georges bayard
Most of those are more so targeted at boys, but fantômette Is targeted at girls, and many girls do appreciate Les Six Compagnons. Think about books like the Hardy Boys or Nancy Drew and you'll have a decent idea of what kind of book series are listed above. The great thing about these series is that they're very, very long, so if you like them, you'll have plenty to keep you busy for a while.
Modern series:
Tara Duncan - Sophie Audouin Mamikonian
Le Souffle de la pierre d'Irlande - Eric simard
La rivière à l'envers - Jean-claude MOURLEAT
La quête d'Ewilan - Pierre Bottero
I'd recommend any of these modern series for a younger girl with the exception of La rivière à l'envers, which I haven't read yet.
Out of all the series from both the classics and the modern series I'd say that Les Six Compagnons Is my personal favorite, but If I had to choose only one that I think the average young girl would like, I'd choose Tara Duncan. That said, all of the above series have their charm.
