Have you read Madeleine L'Engle's Crosswick Journals? I haven't read them all, but what I did read was deeply satisfying. So satisfying, I haven't been back to re-read them because I'm too afraid they won't hold up to more scrutiny. That happens with me and books sometimes. I feel that way about The English Patient and Possession too.

Hmm, maybe The Crosswick Journals are just what I need right now:)
