The Gallifrey Chronicles
Lance Parkin
 The Eighth Doctor accompanied by Fitz Kreiner and Trix MacMillan, overthrows the tyrant Mondova on an alien world, prevents a time travelling alien from interfering in Ancient Roman history and stops a Dalek (never named as such, but heavily implied) invasion of Mars. Against this backdrop, Fitz and Trix have begun a relationship and decide to leave the TARDIS. The Doctor returns to Earth in 2005, materialising at the grave of Sam Jones. When the Doctor claims not to remember his former companion, Fitz becomes angry and leaves with Trix. As the pair attempt to readjust to normal life, it is revealed that Trix has been secretly passing information gain on their travels to another former companion Anji Kapoor who has used the information to manipulate the stock market and thus built up a considerable fortune. The Doctor discovers that another Time Lord, Marnal, had also survived the destruction of Gallifrey and has been living for the past hundred years as a human science-fiction writer (whose books are actually the history of the Time Lords and their homeworld). Marnal, who also claims to be the original owner of the Doctor's TARDIS, blames the Doctor for the cataclysm, and takes him and the TARDIS captive while the insectoid alien Vore invade the Earth. The Vore attack leaves millions dead or missing, including Fitz who apparently dies trying to save Trix. After a cold fusion explosion guts the interior of the TARDIS, the Doctor discovers that K-9 Mark II has been aboard ever since Gallifrey's destruction, hidden behind a false wall, with orders from Lady President Romana of Gallifrey to kill him. However, K-9 pauses once it scans the Doctor's mind and discovers the reason why the Doctor had lost his memory. It transpires that, just prior to destroying Gallifrey, the Doctor (with the help of his former companion Compassion) had downloaded the entire contents of the Gallifreyan Matrix — the massive computer network containing the mental traces of every Time Lord living and dead, more than 140,000 Time Lords — into his brain, with his own memories suppressed to make room for the data. Gallifrey had not actually been erased from history, but an event horizon in relative time prevented anyone from Gallifrey's past from travelling beyond Gallifrey's destruction, and vice versa. Both the planet and the Time Lords could be restored, along with the Doctor's memory, if a sufficiently sophisticated computer could be found to reconstruct them. Before that could be done, however, the problem of the Vore must be dealt with. Marnal is wounded while fighting the Vore, and being on his last regeneration, he dies. The Doctor tells him that he is his hero, and Marnal dies in peace, confident that the Time Lords will be reborn. The Doctor reveals that the Vore have not actually killed their victims, but sprayed them with a chemical that makes them invisible to humans; Fitz is still alive and the Doctor brings him back for Trix, claiming he brought the dead back to life on his first day on the job. The Doctor, Fitz, Trix and his allies travel to Africa with a Royal Navy Battle Group to confront the threat of the Vore. The novel and the Eighth Doctor Adventures end uncertainly, as the Doctor leaps into the very heart of the Vore hive.
