I read the Golden Compass and the two books that follow and I have to say I was blown away. I've been struggling with trying to figure out how to write about god in a non-annoying way while not really knowing what I actually think about god including whether or not he exists. And Pullman just does it. He manages to write about the Christian god many of us know while at the same time taking us into a different world and letting different facets of spirituality and our selves and the good and bad things surrounding religion while telling a highly engaging adventure story.
The greatest thing about it however, is the love story that really only develops in the last book. I don't want to say too much about it because I don't want to give it away and I'm hoping you'll read it. As a lover of love stories, I have to say, this is one of the best I've seen and the way he connects god and love and sin at the end is simply elegant. But these are books that broke my heart and I highly recommend them.
