The time is the future. The place, an America so isolated by fear that it is cut off from the rest of the world by a massive defence system. Into this armed, barricaded state comes a young Russian scientist bearing a strange and almost unbelievable story: Superior, intelligent life - on a far higher order than any on earth - has been detected near the planet Pluto. Immune themselves by virtue of their far greater intelligence, these aliens are about to destroy the planet Earth.
John Brunner (1934-1995)
John Brunner was a prolific British SF writer. In 1951, he published his first novel, Galactic Storm, at the age of just 17, and went on to write dozens of novels under his own and various house names until his death in 1995 at the Glasgow Worldcon. He won the Hugo Award and the British Science Fiction Award for Stand on Zanzibar (a regular contender for the 'best SF novel of all time') and the British Science Fiction Award for The Jagged Orbit.
