The world you came from impacted a lot of people who read about it. It showed us that it's not only a slippery slope between our own governments (Communism, especially) and the totalitarian Big Brother you lived under, but that it's GREAT to have freedom of expression and the ability to be as freaky as you want to be.
You were already a great influence to a lot of us, you just don't know it. Your reality, even if it's fictional to others? Is just as important to us as it is to you. That book makes up a great deal of the reason I believe what I believe.
