Hermione gets sent back in time to 1926 to help fight Grindelwald. She isn't stuck there, she can go back to her own time. She meets Newt, Queenie, Tina and Jacob. Could probably be rated K but I went with T just to be safe.
Hermione has a worse home life than even Harry. Her parents have been abusive for as long as she can remember. What happens when the Order find out?
