Sometime Never...

Sometime Never... is a BBC Books original novel written by Justin Richards and based on the long-running British science fiction television series Doctor Who. It features the Eighth Doctor, Fitz, Trix, and Miranda.

Plot summary
The Council of Eight have set plans for all of time and space. The Doctor's travels are causing difficulties for this plan, so the Council sets off to attack him, and his dear friends.

Continuity
The epilogue of the novel offers a possible explanation to the fan asked question of how the Doctor can still exist after the destruction of Gallifrey in The Ancestor Cell. In that novel, time is reversed to stop Gallifrey or the Time Lords from ever existing, provoking confusion among fans. This novel shows the Doctor giving one of the council of Eight (Soul) some of his life energy to keep him alive. When Soul and Miranda's daughter Zezanne leave in Sabbath's time ship (the Jonah), Soul takes on the form of an old man who resembles the First Doctor. They both lose their memories, but believe they are the First Doctor and Susan. The Jonah arrives, disguised as a Police Box in 1963, with Octan's Starkiller (replacing the Hand of Omega). This potentially retcons the entire series, giving an alternative explanation to the Doctor's origins without the Time Lords.

This however contradicts the revelations about Gallifrey's destruction in The Gallifrey Chronicles, where it is revealed that while Gallifrey was destroyed, the Time Lords were not erased from history. However, the cataclysm set up an event horizon in time that prevented anyone from entering Gallifrey's relative past or travelling from it to the present or future. The Time Lords also survived within the Matrix, which had been downloaded into the Eighth Doctor's mind, with the intention of restoring the Time Lords and Gallifrey.
