Firstly, I am tired of reviewers 'comparing' this trilogy to JK Rowlings Potter Series. Secondly, There is no comparison. Meaning you may as well compare Chocolate with Steak. Both have their place at a well planned dinner table! We need to be reading a balanced meal.
I love The HP books equally as I do the 'His dark Materials' Trilogy.If you're looking to replace the 'Potter' rush with the Pullman books, it won't happen, this is a deeper and darker league. You will find yourself drawn into places and plots, lives and ideas almost impossible for many an imagination. Perfectly written and a great main course after the 'Potter' starter, however, I will be returning to the be-specticaled one for dessert. (The lighter option) Again, I say... No Comparison, maybe complimentary.
Enjoy your time with His Dark Materials,lose yourself in the questions the books will awaken and be prepared to miss your stop if you read it on the bus! I just hope the up-coming film does Pullman justice.
