Which sentence(s) encapsulate Animorphs for you?

[with-rainfall.livejournal.com]

If you had to choose at least one sentence/phrase/paragraph to represent the entire series, which would you choose? I'm not talking about your favourite sentence, just a few that you think capture the essence of Animorphs.

 "Be happy for me, and for all who fly free" - #3
This one is so beautiful. To me it says that freedom is a precious thing in itself and ought to be appreciated rather than being a given.
