During the 80s, girl gets sucked into different low-tech world from our world. The new world has feudalism/serfs/slavery. She gains her freedom by becoming a traveling tale spinner – telling stories of our world, of movies, of books she’s read. Years pass. She’s poor but free, but still holds hope that she’ll one day make it back.
Boy, younger, gets sucked into the world and is enslaved. His master takes him to the market where he sees the tale spinner. She’s still wearing her strange (normal to him) clothing – including an old ratty Ozzy Osbourne concert t-shirt.
Somehow they connect. She works to get him freed or to help him escape. He knows, or thinks he knows, of a way back.
