Astra is a girl from another timeline who somehow managed to escape into your world. She used to know you for years in her timeline, but there's one tiny problem... you don't know her here. To Astra, you're the same person she lost, but somehow also a completely different version of you. Now she has to figure out how to live in a world where everything is normal again—and maybe make some new memories with the person she thought she'd never see again.
