Philip Pullman has written a new book, described as a “must-have” companion to his epic His Dark Metrials.

The Imagination Chamber will reveal new scenes set during the events of Northern Lights, The Subtle Knife and The Amber Spyglass, as well as companion novels La Belle Sauvage and The Secret Commonwealth.

According to the publishers, the book will offer new insight into the story and lives of iconic characters such as Lyra, Will, Mrs Coulter, Lee Scoresby, Pantalaimon and Iorek Byrnison.

It will include scenes such as Serafina Pekkala listening to Dust on her cloud-pine broom, Lyra’s childhood speculations about her absent mother and new insight into daemons.

Pullman said: “I’ve always been fascinated by the little grains of dust (or Dust) that can grow into stories in the imagination chamber of the writer’s (and reader’s) mind. Here are some of those minute specks of vision, any of which could grow in any direction: pictures before they become visible. I hope readers enjoy letting them develop.” 

The Imagination Chamber will be published on 28th April.
