Whereas I read this before anything else, so always had Christopher in my head; the fascinating bit was seeing who he ended up being as an adult.

There's an odd split for me, between the books of hers I read as a kid and those I read later (the dividing line more or less being around the start of college). I don't think there's anything in that later grouping I love as much as my favorites from the early days, and it probably has to do with that change in perspective, as much as (or more than) a change in the books themselves -- by then I was mostly reading newer material as it came out. A lot does depend on one's life context, as well as the story.
