While reading this book, I was really confused about the title. In the second book of the His Dark Materials trilogy Will's subtle knife wasn't introduced for a long time and although I like the story I think that the title of this book could have been better. It kind of distracted from the story that during the beginning I was always wondering how a knife would play into the story. I also didn't think that the characters were really well developed. Mary Malone just walked through the tent in the middle of the story and that was it. We didn't know much about her and then she just walked away and that was it. And what happened to the other characters? I guess I will have to wait for the last book to get those questions answered. Other than those things, I thought that this was a great story and Lyra has really intrigued me to want to read more. The first two books in this trilogy had really suspenseful endings. It was as though the story stopped mid scene and I was left hanging, so I can't wait to get the next book!
