The Unseen World is a quiet, beautiful story that kind of sneaks up on your emotions. It starts with a girl and her brilliant, quirky father, then slowly unravels into this mystery about who he really was. It’s part coming-of-age, part techy puzzle, and part emotional gut punch. If you like books that are smart but still have a lot of heart, this one’s a great pick. It’s thoughtful, moving, and lingers after you finish.
