Someone might try to describe this book to you by telling you a little about it's plot. It's got some classic archtypes, and it's got a great deal to do with loss of innocence. It's basically about a little girl trying to save her friend. Along the way she meets new friends, including talking polar bears and gypsies. And you might think 'Oh, it's just another children's book.' And you'd be completely wrong.
THE GOLDEN COMPASS (which was released in the UK under the title THE NORTHERN LIGHTS) is typical Pullman-- intelligent writing, complex characters, fascinating world. It's everything a good children's book ought to be. It's a great read no matter how old you are.
Lyra is a really interesting character. At first, she is bratty and almost completely unlikeable. But by the end of the book, I adored her. She is brave, resourceful, clever, and resilient.
This is a book that I find myself reading once or twice a year. It's got a gripping story, dynamic characters, and is superbly written.
I'd recommend this book to anyone who likes Pullman's other books, a good fantasy story, and to anyone who's looking for something good to read while we wait for the next Harry Potter book.
