The Gallifrey Chronicles is a BBC Books original novel written by Lance Parkin and based on the long-running British science fiction television series Doctor Who.

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.

The Vore attack leaves millions dead or missing, including Fitz, who apparently dies trying to save Trix.

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.

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.

The Doctor, Fitz, Trix and his allies travel to Africa with a Royal Navy Battle Group to confront the threat of the Vore.

Marnal gives a list of some of the Eighth Doctor's companions, including some not mentioned before: Delilah, Frank, Deborah, Jemima-Katy, Nina, and Beatrice (possibly Trix[citation needed]).

These include Omega (The Three Doctors), the Sontarans (The Invasion of Time), Tannis (Death Comes to Time), Varnax (from an unproduced film project[citation needed]), Catavolcus (the Doctor Who Magazine comic strip story The Neutron Knights, DWM #60), and the Timewyrm (Timewyrm: Revelation).
