If you want the emotional punch and the story beats to land exactly as Pullman designed them, I’d recommend reading the original trilogy first: start with 'The Golden Compass' (published as 'Northern Lights' in the UK), then 'The Subtle Knife', and finish with 'The Amber Spyglass'. That sequence preserves the surprises and the way the world slowly expands;
the mysteries feel earned and the characters’ arcs resonate
more if you follow the books in that order.
after the trilogy, ease into the 'Book of Dust' novels — read 'La Belle Sauvage' next (it’s a prequel that deepens Lyra’s backstory but doesn’t spoil the trilogy), followed by '
The Secret commonwealth'. Sprinkle in the short pieces like 'Lyra's Oxford' and the novella 'Once Upon a Time in the North' wherever you like for flavor; I usually
read them after the trilogy so little cameos and hints enrich rather than spoil the main story.
There’s a chronological alternative (starting with 'La Belle Sauvage' before Lyra’s original adventures) which works if you prefer linear timelines, but I still love the publication order for the emotional ride. Listening to the audiobooks for the trilogy also gave me a different intimacy with the characters — it’s a treat if you can. Happy reading, and enjoy how that compass spins you into something unforgettable.
