One's Core - Outlander Fanfic

Losing a parent can be hard, and Elena Randall believed that her father's passing was taking a toll on her mother's mental well-being, believing her to be going insane. Only to receive letters from her now missing mother and sister about time travel laced with mystery, surely their contents aren't true? Will she be led on a goose chase or an adventure with no clear path in a different time?

One's Core can also be found on Ao3 :)
