In brief, the books follow the adventures of Lyra (and later on a boy named Will) ... but "adventures" sounds so cheesy. The reader follows them as their worlds are torn apart and they embark on a quest to actually save lives and to find out what "dust" is, and travel between physical worlds or alternate dimensions...it's really hard to explain in a few sentences.
This is not your typical children's book. There is theoretical physics and some religion bashing, characters die and are tortured and the reader is dragged through every emotion. I felt challenged even as a medium-sophisticated adult reader. And I grew to love all the characters.
It's a shame they tried (and failed) to make a movie of these books, if you've seen the movie please disregard it entirely and read them.
“I'll be looking for you, Will, every moment, every single moment. And when we do find each other again, we'll cling together so tight that nothing and no one'll ever tear us apart. Every atom of me and every atom of you... We'll live in birds and flowers and dragonflies and pine trees and in clouds and in those little specks of light you see floating in sunbeams... And when they use our atoms to make new lives, they wont' just be able to take one, they'll have to take two, one of you and one of me, we'll be joined so tight...”
-Phillip Pullman, a quote from The Amber Spyglass.
