To make matters worse, Moon base personnel inexplicably vanish and vital weather control equipment is sabotaged. Who is responsible? The Director of the base suspects the time-travellers. The Doctor fears that the ruthlessly evil Cybermen are at work.
An exciting unabridged reading, with music and sound effects, this is a novelisation of a classic Doctor Who adventure, first published by Target Books in 1974.
