Re: The Book of Dust
It’s been a long time since I read the original trilogy, so I had to look up a lot of the references.
The things that struck me most were the changes in understanding how Lyra’s world works: The supernatural elements encountered in the flood, which went far beyond what I remember, and the discovery that the Magisterium’s solid grip is so recent.
(That and the migraine auras. I’ve never encountered a character who experiences them, and the descriptions were spot-on.)
