The novel “Deep Time” by Trevor Baxendale was published for the first time in 2015.

The Twelfth Doctor and Clara Oswald embark on the Alexandria, the luxurious starship built by Raymond Balfour. The aim is to discover the last wormhole that in the distant past was part of a vast network built by the Phaerons, a once very powerful but now-vanished civilization.

For some members of the expedition, the discovery of the last wormhole in the Phaeron network would be the feat of a lifetime. However, the Doctor knows that behind the disappearance of the Phaeron there are dark secrets that go beyond the known legends and involve the Time Lords.
