Publisher's summary
When the evil Time Lord known as the Nine comes across a rare and valuable item floating in the space-time vortex, his acquisitive nature means he can't resist the urge to complete the set.

Soon a wicked scheme is underway. Only the Doctor's friends – past, present and future – will be able to stop him.

But without the Doctor around will even the combined skills of Liv, Helen, River Song, Bliss and Charley be enough to save the day?

Worldbuilding

 * The Doctor told River Song about the Nine, "as in the One and the Two, etc".
 * The Nine steals Romana from a time when she is President of Gallifrey, Jamie from a point some time after he travelled with the Doctor, and Adric from a point mid-way through his travels with the Doctor.
 * When the Nine says he's bringing Charley some company, she asks if it is C'rizz, but the Nine states that he intends to leave that maniac alone for a while.
 * The Nine expresses distaste for River identifying a penguin as a companion, with River arguing that the penguin was perfectly valid from a certain perspective.
 * The Nine steals River Song's vortex manipulator.
 * Before the Time War disrupted history, Bliss studied robotics and computer science rather than temporal mechanics.
 * When the Nine tells Charley he wants the complete set of the Doctor's companions, he says "Gotta Catch 'Em All", a reference to the slogan for the Pokémon series.
