Ready Player One

In high school, this was hands-down my favorite book. I reread it a few times in a year because I liked it so much. Reading it now as an adult makes me realize that, while you've got to admire the level of detail and commitment that the author (like Halliday himself) put in, there are more important things. I want more out of a book than just leveling up past stages in a video game.

More mature content than I had remembered.
