7.1 The Sons of Kaldor by Andrew Smith
Finding themselves in a seemingly deserted spaceship on an alien world, the Doctor and Leela stumble into some familiar foes - the Voc robots from the planet Kaldor - and… something else. Something outside. Trying to get in.
Reviving the robot’s Kaldoran commander from hibernation, the travellers discover that they’ve found themselves in the middle of a civil war. The ship was hunting the Sons of Kaldor, an armed resistance group working with alien mercenaries to initiate regime change on their homeworld.
But now the Sons of Kaldor may have found them. The Doctor and Leela will have to pick a side. Or die.

When attacked on an alien world, Leela falls unconscious… only to wake in another time, another place.
She is in the Crowmarsh Institute on Earth, in London, in 1978, and everyone is calling her Doctor Marshall. They tell her the world she has known is but a fantasy, a delusion, and that this place is the one that is real.
Surrounded by familiar faces on unfamiliar people, Leela knows what is true and what is false. But how long can she believe when everyone around her says it’s a dream? What’s really happening here?

The Doctor, Leela and K9 arrive in the city that covers all of this dying world as it prepares to evacuate its people, and they immediately find themselves involved in a mystery. Who or what is responsible for the wave of death? Is it the motorised cult known as the Digitals? The enigmatic Mr Shift?
Or did all the victims attempt to run the Night Mind, the demonic consciousness of legend that is so twisted and evil that it drives mad all who touch it?
The TARDIS crew are about to find out.
