When I was young, Lyra Silvertongue from His Dark Materials by Philip Pullman. A highly intelligent girl who is curious, fearless, and doesn’t let anyone tell her what to do. A bit of a troublemaker.

Now, probably someone closer to The Mercenary Librarians by Kit Rocha. Strong women who work to better their community in a dystopian world, all while going on missions to save books and literature. (I use my library branches a lot, I purchase from indie bookstores, I buy cheap used books at the library bookshop and deposit them in neighborhood little free libraries, etc.)
