When I was nine years old, a wise old woman gave me the book Jonathan Livingston Seagull. After I had ripped through the thin volume, she then turned me loose on Illusions. I've read both of those stories many times over the years, and have in turn over the years passed them on to other children. Even though they aren't necessarily children's books, they made an impression on me at an impressionable age. I have returned the favor.
