'The Doctor will be eliminated. The invasion must proceed.'
Bringing Jamie and Zoe to Earth, the Doctor meets up with Brigadier Lethbridge-Stewart, now in charge of the newly formed UNIT. He is investigating International Electromatix, an electronics firm where the machines seem to have taken control. Many people have entered International Electromatix, fewer have returned, and they have all been — changed. The Doctor soon realises that his old enemies the Cybermen are involved. Will he find their hidden army in time to stop the invasion?
The first story to feature UNIT, The Invasion was written for television by Derrick Sherwin. This novelization is by the late Ian Marter who played the part of the Doctor's companion Harry Sullivan from 1974-75.
