I became friends with someone at my highschool mainly because he read Animorphs. We saw each other sitting at separate lunch tables, reading the latest issue, and started hanging out ever since. He knew a guy that worked at a store that got the latest issues about as soon as it was possible to get one, so he was quite up to date.
Sometimes I wonder what he thought of the progressive darkness of the later books, and the ending. Alas, I graduated before then and never saw him again.
