Doctor Who fans can now pre-order Shada, a full-length novel of the only TV story never completed.

Originally intended to form part of the show’s 1979-80 season, the story was never completed due to a strike at the BBC during filming.

In 1992 BBC Video released the story using linking narration by Tom Baker to complete the story and in 2003 the official Doctor Who website webcast an animated audio play of the store.

The Doctor’s old friend and fellow Time Lord Professor Chronotis has retired to Cambridge University – where nobody will notice if he lives for centuries. But now he needs help from the Doctor, Romana and K-9.

When he left Gallifrey he took with him a few little souvenirs – most of them are harmless. But one of them is extremely dangerous.

The Worshipful and Ancient Law of Gallifrey isn’t a book for Time Tots. It is one of the Artefacts, dating from the dark days of Rassilon.

It must not be allowed to fall into the wrong hands. And the sinister Skagra most definitely has the wrong hands. He wants the book. He wants to discover the truth behind Shada.

And he wants the Doctor’s mind…

Written by Gareth Roberts, the novel is based on the original TV scripts by Douglas Adams.

Set for release on 25th March, Shada can be pre-ordered from and . An eBook version for Amazon’s Kindle ereader and Apple’s iBookstore is also available.
