Blurb – Lower Cover
Aggression is out of date
After one war scare too many the human race has suppressed its aggressive instincts by genetic manipulation.

Make love, not war
Now mankind is faced with an enemy so superior, so ruthless, that it is fight or be wiped out – and humans can no longer fight; they cannot even order their robots to fight.

Violence is decadent
Only a museum exhibit from a thousand years ago – a Royal Navy submarine complete with commander and crew, their belligerent natures intact – can hope to save the planet from an enemy to whom living space is all-important and human life entirely superfluous.

A crisp adventure story’
Daily Telegraph

‘Amusing and ingenious . . . the plot has some unusual twists’
Edmund Cooper, Sunday Times

’Philip E. High is rapidly becoming one of my favourite science fiction writers; his flights of fancy are so firmly attached to a possible reality’
June Francis, Morning Star
