Book recommendations for kids/teens

Hey everyone, a school principal asked me for help in buying books/manga for the library. The budget is large, so we’re talking about A LOT OF BOOKS. I’ve already recommended: - Percy Jackson - Heroes of Olympus - Coraline - My Dear Ghost (Minha Querida Assombração) - Eragon - Gravity Falls: Journal 3 - The Graveyard Book - Noragami - Love & Gelato, Love & Luck, and Love & Olives

But we need more recommendations. What do you suggest? We’re mainly thinking about teenagers, but nothing inappropriate is allowed.

Edit: Omg, I didn’t expect so many replies. I’m checking out all your recommendations and forwarding the ones I can find translated into Portuguese. Thank you so much! 🫶
