War Storm is the big, heavy finish to a series that defined the late 2010s YA scene. It’s not a light read. It’s moody, it’s violent, and it spends a lot of time on the logistics of revolution.

If your teen has made it through the first three books, they’re already committed. Just be ready for them to have some big feelings about the ending—it’s more 'bittersweet realism' than 'happily ever after.' It’s a solid piece of literature for exercising those empathy and critical thinking muscles, even if it feels like a marathon to finish.
