A new series of Doctor Who stories is set to be published monthly to celebrate the 50th anniversary year of the hit television programme.
The 11 tales, known as “eshorts”, will each be written by a well-known children’s author.
Each story will feature one of the various regenerations of the Doctor, starting with William Hartnell, who played the character from 1963-1966.
A paperback of the stories will be published by Puffin in November.
The first children’s author will be revealed on the BBC Worldwide Doctor Who Facebook page on Monday 7 January, followed by the first story on Wednesday 23 January.
A promotional video of each author will also be available each month on the BBC Worldwide YouTube channel starting on Friday 11 January.
