The Hunger Games, as it’s easy to read but also has a lot to say about challenging a Communist regime. It was assigned in high school back in 2010. So at least one English teacher saw some literary value in it.

Incredible.

Start with The Hobbit, then the LOTR trilogy.

If you like it enough look into The Silmarillion and others like The Children of Hurin, which really flesh out the lore etc.

I’ve read The Hobbit and LOTR many many times over the years and only now gotten around to reading The Silmarillion etc.
