What perspective is the author telling the story from?

My new book is called The Amber Spyglass, and it is written by Phillip Pullman. This book is the 3rd in the His Dark Materials series. All of these books are written from changing perspectives. First the author opens the book from a small girl named Lyra's point of view. But very soon, it switches to (her mother)Mrs. Coulter's point of view. And all through the story, the author keeps switching points of view to give the reader all the information they need to fully enjoy all the different feelings and emotions each character feels. So to answer the question, Phillip Pullman doesn't actually take just one point of view, he takes all of them! And that is the really cool thing about his writing!
