Unmoored

In so many stories, a girl from our world falls into Middle-Earth after she dies in some horrible accident. But what if it wasn't a one-time thing? What if you couldn't turn it off? What if every time you died, you woke up in another universe? It sounds cool at first, but eventually it would become a living hell, wouldn't it? Post-BoFA, but includes flashbacks to the quest.
