Yoo guys so the thing is I remember exactly one thing from the whole book, i don't even know if it was an english book.
The thing I do remember is there was a girl that had been held captive in an underground cave to braid ropes...? And she could braid up to 12 strands, and when she found some slow worms in the complete darkness, she braided them too.

That's literally all i remember. I know it sounds like a fever dream, but I swear it's a real book lol.

Well now I'm curious

What kind of genre was it? Fantasy, fairytale, YA, Historical Fiction...? And about what age level of reading?

Phew man... I'm really not sure anymore. Guess it was for teens.

Sorry I don't have much hope for this :D
Unless one of y'all posts this somewhere else as well.
