Bloomsbury is to publish novella The Pale Dreamer, the "exhilarating" prequel to the Bone Season series by Samantha Shannon, as a December e-book (112 pages, £1.99).
The publisher acquired world English rights from David Godwin Associates.
The novella will tell the story of clairvoyant Paige Mahoney and how her "gifts" came to light. It is promised to be an "exciting" introduction to criminal underworld Scion London, and the world of the Bone Season.
The first book in the seven book series The Bone Season was published by Bloomsbury in 2013. It has been translated into 28 languages and the film rights have been acquired by The Imaginarium Studios and 20th Century Fox. The third novel in the series The Song Rising will be published in March 2017.
Shannon said: "I'm thrilled to be able to expand the world of the Bone Season, and to show everyone a different, younger Paige, in The Pale Dreamer. I hope it gives readers something to look forward to before The Song Rising comes out in March."
The Pale Dreamer will be out as an e-book on 6th December. It will also be included as additional material in the rejacketed paperback edition of The Bone Season in February 2017.
