Genocide (novel)

Publisher's summary
Years after leaving UNIT, Jo Grant receives a plea for help from an old acquaintance. A palaeontological study of the earliest known humans is apparently under threat from a UNIT force led by a captain who does not officially exist. Investigating further, she begins to find herself out of her depth - and out of the twentieth century altogether...

Meanwhile, the Doctor and Sam visit Earth in 2109 - but there is no trace of the human race. Earth is home of the Tractites, a peaceful race who have been living there for hundreds of thousands of years. Astonished and appalled, the Doctor travels back in time to see just what went wrong in Earth's prehistory.

Why have Jo and the expedition been taken back in time? Are the Tractites all they seem? Finally, separated from the TARDIS, the Doctor's last chance to put things right rests with Sam - but has even she turned against him?

Continuity

 * DW: The Green Death introduced Cliff Jones and showed him and Jo planning to get married.
 * The last contact the Doctor had with Jo was in the form of a letter (DW: Planet of the Spiders)
 * The model train set from ST: Model Train Set is seen.
 * The Doctor mentions Davros in this novel and later meets him in EDA: War of the Daleks.
 * Jo saw the jungles of Spiridon in DW: Planet of the Daleks, Axons in The Claws of Axos, Sea Devils in The Sea Devils, Autons in Terror of the Autons and Xarax in MA: Dancing the Code.
 * The depiction of Jo in this book is somewhat difficult to reconcile against her later appearance in SJA: Death of the Doctor. We can perhaps imagine that this book takes place in a "rough patch" of Jo's marriage, but she is well and truly on her own here. The word "divorce" doesn't appear in the book, but it's clear she has total financial responsibility for her and her child. Moreover, she's only got one child in this story, Matthew, and he's just started high school. Death to the Doctor says she's got 7 kids. It's hard to see how she could have six more kids after Matthew, with Cliff, starting at roughly the age of 35. Additionally the separation/divorce from Cliff has left her having to hold down two jobs in Hackney. How exactly she was supposed to be globetrotting given this somewhat bleak reality is unclear.
