I just read this in one sitting and my mind is fizzing with excitement about this extraordinarily brave autobiography, social history, family history, and intimate (sex!) details. I have to admit that my own "light cone" (google that!) is congruent with Maggie's: post-war Britain, grammar school, Oxford undergraduate in the mid 1960s, all the confusion of womens' lib. Here is a jewel of a book in which the way we lived back then (1948 - 1968) is told with such feeling of love, and of the joy of simply existing. As a historian of astronomy, I admire Maggie's reflection that our home planet existed four billion years before our birth and it will survive as a planet for four billion years after our death. So we are here (yes, that includes you Dear Reader) for an instant between two flaps of wings somewhere in the cosmos. So what's it all about? Maggie (she prefers that name to the Margaret her parents gave her) is deeply moving (and Reader note that I am a male ...) on the importance of love within the family and our friendships. Her penultimate chapter is titled "What is a soul?" It is inspirational for anyone who was brought up in the Christian faith but is now a non-believer.
