Any book recommendations on advanced/challenging topics for Econ?

I'm currently a high school junior and interested in pursuing economics in college. I have already read books like Freakonomics, Naked money, Naked Economics, and some stock books, but I want to get into some advanced or more challenging econ books. I am also currently doing FBLA and am waiting to see if I get to states for Econ. Many of the questions are quite broad and often are macro, so I feel like reading some books may help too. I am open to any recommendations and not just ones that are hard. I would love to get some nice reads. I am not afraid to dive into some math and stats for econ since I know it is important. Thank you
