I want adult Luna Lovegood travelling back in time because she's woken up in a world where her husband and child have vanished, Newt Scamander's book doesn't exist, and Grindlewald is in power (possibly with a young lieutenant called Tom Riddle).

She's the only person who remembers what her world is meant to be like, and everyone thinks she's crazy - no change there them. But she's figured out that Newt was the turning point, and she's got hold of a time turner and followed somebody back in time, Terminator-style, to set History back on track by saving Newt Scamander's life from the time-travelling dark wizard who's come back to destroy Newt and enable Grindlewald to flourish.

I want BAMF Luna, nerdy creature-loving bonding, time-travel highjinx and swashbuckling adventure.
