The Amber Spyglass is really a sequel to The Subtle Knife more than a conclusion to The Golden Compass . Most everything that I liked in the Golden Compass but was missing in The Subtle Knife is still missing here, while the new additions that annoyed me about The Subtle Knife are turned up to 11.
We get fascinating new worlds (miniature spies with poisonous spines on their feet! creatures with wheels! how weird!) but to the most part they don’t seem to really lead to the story. Lyra… is growing up and supposed to be super important to the upcoming battle, but really this is again a book about Will. And Lyra’s big part? Growing up. That’s about it.
