Doctor Who: The Invasion (Target Doctor Who Library, No. 98)

The Doctor remembers Dulkis from a previous visit as a civilised and peaceful place. But times have changed, and his second trip is not quite the holiday he was expecting. The Dulcians themselves are more reluctant than ever before to engage in acts of violence. The so-called Island of Death, once used as an atomic test site, has served as a dire warning to generations of Dulcians of the horrifying consequences of warfare. But an alien race prepares to take advantage of their pacifism... The whole planet and its passive inhabitants are threatened with complete annihilation - and no one it seems, is going to lift a finger to stop the evil Dominators and their unquestioning robot slaves. Materialising in outer space, the TARDIS is attacked by a missile fired from the dark side of the moon. Back on Earth, the newly-formed United Nations Intelligence Taskforce, led by Brigadier Lethbridge-Stewart, is disturbed by a series of UFO sightings over Southern England. Meanwhile, a large consignment of mysterious crates is delivered to the headquarters of International Electromatix, the largest computer and electronics firm in the world. Three seemingly unconnected events but in reality the preparations for a massive Cyberman invasion of Earth with one aim the total annihilation of the human race.
