If you like sci-fi,
The Moon Is A Harsh Mistress is a great book. So is Heinlein's
Starship Troopers (the movie did no justice to the book).
Another good read is Voyage From Yesteryear by James P. Hogan.
All have interesting political undertones.
My voice hadn't changed before I read all of those. I grew up on them. When I was 12, I bought a hardback copy of 'Time Enough For Love" of my own. With money that I had earned.
My parents didn't have a clue, and I didn't clue them in.
Heinlein, via his writing, was my mentor, from ages 7-10. Quite an impressionable age.
