If you are a teenager it will definitely make you think and likely leave an impact on you. It's not a typical novel, more like philosophical ideas presented in the form of a novel. Ideal characters placed in real life. You will also understand why the world is divided into Ayn Rand lovers and haters.
It questions how the world works, how it should work, how people live their lives, and how they should live their lives, etc, etc.
Warning you, it's not filled with plots twists.
