Fan Casting His Dark Materials: The Subtle Knife

The Subtle Knife is the second in the His Dark Materials Trilogy. It follows on from Northern Lights (The Golden Compass) by adding a new protagonist Will, who, around the same time as Lyra discovers a window to gain access to Cittàgazze, a world haunted by Spectres and a city inhabited entirely by children. During this book Lyra starts getting a bit less selfish and begins to realise some of the true intricacies of the alethiometer. This book also deals a lot with the matter of Dust or Dark matter. It also begins to explain about Lord Asriel's rebellion against The Authority and the church. This book sets a much darker tone to the series and adds more meaning to the characters' actions in Northern Lights.
