Vor (1958)

Here is James Blish's novel written with brilliance and astonishing realism - about that ultimate moment in time when -

THE FIRST ALIEN FROM OUTER SPACE ARRIVES ON EARTH:

How "it" communicates and what "it" wants.

How we greet "it" , nourish "it" , communicate with "it".

What we learn from "it" of interstellar worlds, galactic powers, the void beyond.

And how, in the terrifying moment of Earth's ultimate crisis - we defend the complex civilization of tomorrow from "it!".

THIS COULD HAPPEN TOMORROW, OR THE NEXT DAY - BUT THE AWESOME MOMENT IS CERTAINLY WITHIN THE REALM OF POSSIBILITY - AND MAY BE CLOSE AT HAND!
