Query: Fun and Intriguing Page Turner

As an adult reading Philip Pullman for the first time, I was fascinated by the gutsy protagonist and her search for the truth about her past. The plot has lots of twists and turns with so many characters that it doesn't all hang together as well as I would have liked. The ending contains several unexpected surprises and enough interest for me to read its sequel.
