   Summary

   Hermione Granger knew about time-travel and time-turners as a third year. When everything goes wrong at the Battle of Hogwarts, and nearly everyone she loves dies, Hermione discovers that not only is time-travel possible within her world but across worlds as well.

   Suddenly thrown back to 1978 and into a world that is no longer her own, Hermione has a chance to rewrite history, because while terrible things happen to Witches and Wizards who mess with time, she doesn't think that applies to a Universe where she never existed in the first place.

   Never one to back down from a fight, Hermione is going to make this new world a better place. She's going to take down Voldemort, avoid an ever Manipulative Dumbledore, and she's going to do so alongside an equally war-battered George Weasley and Draco Malfoy, and maybe with the help of a young Severus Snape.
