I cannot for the life of me remember which of these books was which, or what happened in which. They really are mostly all one book, a la Lord of the Rings, just split up to increase sales/commercial appeal. I also, tragically, can't remember individual plot points. I remember the gist, I remember writing a kickass paper about them, ad I remember lots of complicated thoughts and notions about religion and evolution. Also, I remember them being really amazing, complicated books, and being surprised that they're "children's books".
