9/10. I read this book twice ready, and might revisit it latter. I love the world building of Pullman, and the way he tells the story as well. However, some passages felt too hasty for me and imho could use more words to explain what is indeed happening and why is it happening (mostly on book 3). All in all, this is a superb series.
(FTR: This version isn't censored like the American one)
This kindle book is great as it is 3 books in 1. It saves space in your kindle list view. As for the story, it is one of the best book I ever read. Far better than the movie. I do recommend the reading. You will only stop reading when you reach the last page!
