I can't begin to say what A Wrinkle In Time meant to me, as a bookish, sheltered 11 year old. It changed my life, and I loved that book unreservedly (staying my favorite book until I read Pride and Prejudice in my 20's, by which time I had already met and married my own Calvin). I recently started reading Wrinkle to my 6 year old granddaughter- we don't see each other as often as we'd like, so it's going to take awhile to get through the story,but we're enjoying it enormously (and I am seeing it again, as a child, something I haven't done for 40+ years).
Though the later books in the series don't hold up to the original, Wrinkle is a wonderful and powerful book. And I am so sorry that Madeleine L'Engle is writing no more.
