Thunderous warfare in interstellar space.

Ravaging through the far reaches of space was an alien race of reptilian beings who compulsively destroyed every civilization they found... and now they had heard of Earth.

Perry Rhodan and his Third Power were man's only hope against these marauders, and Rhodan did not hesitate to fight - he immediately went out into distant space, to the planet-system of Vega which was under attack by the aliens now, to try to fend them off from his home-world.

But in the Vega sector, Perry Rhodan suddenly found himself facing extinction... and all the hopes of Earth would die with him.
