I'm sorry to say that Pullman's main achievement in this last book is to create yet another soppy paean to adolescence. I was really disappointed in the weakness of the plot and characters. Through most of the book, Pullman is crudely trying to jerk the reader's emotions around... Oh, the sadness! Oh, the joy! Oh, the tragedy! It's all surprisingly amateur, simplistic, and it doesn't work. At least not for an adult reader. But I couldn't like this kind of sci-fi hackery even when I was an adolescent myself. Oh Asimov, Tolkien, where are thou???
