His Dark Materials

Following Lord Asriel's tear through the worlds, Lyra and Pan journey to the strangely deserted city of Cittàgazze. Whilst the Magisterium refuses to acknowledge this new world exists, Mrs Coulter interrogates Katja, an imprisoned witch. Lyra crosses paths with Will Parry, who she reluctantly teams up with. While exploring the city, they meet children who warn them about Spectres. Although children are unaffected by Spectres, they can consume the souls of adults.
At the witch council, Lee Scoresby reveals he is seeking out an explorer who could offer Lyra protection. Against Serafina's wishes, Ruta tries to rescue Katja. Lyra realizes there is an Oxford in Will's world too, and he reluctantly agrees to take her.

Upon crossing through to Will's world, Lyra finds it to be very different to her own. After encountering the enigmatic Charles Latrom, they head to find a scholar to help get answers about Dust. Lyra meets Mary Malone, who reluctantly agrees to let Lyra interact with ‘the Cave' - and is astonished by her results.

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.

Will and Lyra plan to steal the alethiometer from Boreal but are set back by an unforeseen guest. MacPhail takes decisive action, and Mary takes a leap of faith.

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, the search for Will's father becomes more pressing. Jopari and Lee try to locate the knife bearer, but the Magisterium are in close pursuit. Ruta updates Serafina on Asriel's plans, but Serafina insists her duty is to Lyra. Mary consults the I Ching on her task after bidding goodbye to Angelica and Paola.
