Lyra and the Gyptians arrive in the North and seek the help of the Witches’ Consul, Texan aeronaut Lee Scoresby and an armoured bear in service to the town.

The alethiometer sends Lyra and Iorek on a new path, leading to a shocking but vital clue in her search to find her friend Roger and the other missing children.

Lyra discovers the horrific truth behind the Gobbler’s activities in the North. She must use all her wits to help free those around her and avoid suffering a terrible fate.

Separated from her friends, Lyra must use all of her methods of deception to thwart a formidable foe. Meanwhile, Mrs Coulter plots her next move.

Lyra and Will find themselves in a strange new place. The Magisterium take action as Mrs Coulter interrogates a suspected heretic witch, and Lee Scoresby embarks on a mission.

Lyra ignores the alethiometer, with dangerous consequences for her and Will. Lee Scoresby’s search for Grumman brings an unlikely ally, and the witches seek answers.

In search of the knife, Will and Lyra try to gain entry into the Torre Degli Angeli. Lee finds Grumman - or Jopari, as he is now known - and they take to the sky in search of the knife bearer.

Lyra and Will find allies who can help them in their search for Will’s father. The Magisterium learn something shocking, and Mrs Coulter meets a formidable foe.

As all paths converge on Cittàgazze, Lee is determined to fulfil his quest, whatever the cost. Mrs Coulter’s question is answered, and Will takes on his father’s mantle.
