The Rocket Invaders (en Inglés) - Robin St. Clair

August, 1961. They came from beyond the stars - and nothing humanity had would be enough.

When radio signals of unmistakably alien origin begin growing stronger, brilliant and unconventional scientist Dr. Roberta Swift suspects the worst. She's right. Within days, a vast armada of rocket ships descends on Earth, bringing with it an unstoppable tide of horrific alien beings and deadly technology

The Rocket Invaders follows an unlikely cast of heroes thrown together by catastrophe: an experienced American paratrooper, a sharp-minded IBM keypunch operator, a decorated Soviet field marshal, and a headstrong scientist who must outwit a terrifying and unsympathetic alien intellect.

Set against the backdrop of the early Space Age, this sweeping science fiction, alternate history adventure pits humanity's ingenuity, courage, and stubborn will to survive against an enemy that has conquered worlds - and has never lost.
