Publisher’s Blurb – Lower Cover
Twenty-seven light years from Earth, was Ferrol, eighth planet in the Vega system. There, Perry Rhodan, peacelord of the Universe, discovered that the race of Immortals had landed many thousands of years ago but a catastrophe had – despite their immortality – swept the race into extinction.

There was, however, one survivor who decided to find a worthy successor to his immortal secret. He devised the galactic riddle, which so far, had led Perry Rhodan and his Mutant Corps through the vast reaches of space to no avail.

Now Perry had found a new clue which demanded he travel through time . . .
