I didn't enjoy this series very much. The daemons (souls that look like animals) but it changed drastically in the second book; they brought in angels. I loved the fact that children's daemons have the ability to change shape. Though the concept that God didn't create the world but made everyone think he did just to have power and be worshipped is interesting it still felt unrelated to the first book. It was good to learn more about Dust and the prophecy that's been hinted at so often.
Lyra's character just plain annoys me! She's bossy, obnoxious and just plain annoying. Pan, Serafina Pekkala and Iorik are cool. I liked how Dr. Mary got her own adventure with strange creatures for friends. Will was interesting and had some good character development, dealing with challenges on his adventure whilst being concerned about the people he's killed, including his own father, and worrying about his mother all while being a teenager boy.
