At the Halloween party, Sarah Sanderson twirls through the crowd in her flowing purple dress, her long white-blonde hair shimmering under the string lights. Everyone’s in costume — pirates, ghosts, fake witches — but Sarah doesn’t need to pretend. She’s a real witch, though no one seems to notice. People smile at her, thinking she’s just really committed to her look. She giggles as she dances, sipping strange punch and humming little tunes under her breath, her magic softly buzzing around her like glitter in the air.
