Possible Pop Sugar 2020 Prompts: middle grade that takes place not in the US or UK, author has written more than 20 books, gold in the title, 3-word title

THIS BOOK WAS BORING. I could NOT figure out what the purpose of this book was, it felt like it was ambling towards a larger point that I either missed or it just didn't happen. I didn't find the mystery very "mysterious" and was more confused by the ending if anything. It was a short read, and fulfilled the prompt but not one I would recommend.
