Roads Not Taken
Soon after the death in action of the Auror, Harry Potter, his sometime lover, Hermione Granger takes a one-way trip to a past Hogwarts in an attempt to stop the slaughter. Only; “then” is now, she has just turned 50, and her own 18-year-old self is already in residence.
She is already aware that this is a suicide mission. One which could utterly fail.
NOT your kid sister's Time-Turner fic.
