So, lots of fascinating tidbits, stories and observations here. She's especially good on numbers and the scale of the world and our place in it, and doing her best to make you feel humble and insignificant, which is nice. And the stuff about birth defects is eye-opening (and eye-watering).
Less interesting, for me at least, was all the stuff about theologians' debates about the nature, powers and attitudes of God. And the way she hopped from one story or thread to another in the space of a few lines was irritating. Maybe she was challenging us to find the connections, and there were some, but at other times it read like random jotings in a notebook, and I prefer my books to be a little more...finished.
