Nothing But Reading Challenges discussion

Hi!

I'm gonna join the ToTathlon for October and I can't think of a book where "someone gets lost (and/or find themselves).

I'd really like book recs about people getting lost, and if possible in fantasy/sci-fi/ya-fiction genres (or adventure), that could fit into Halloween reads. Any ideas?

Has witches and monsters and a girl gets lost in the woods.
Mom and daughter get lost to each other and then found.
