In book 13 of this Space Opera, Rhodan & crew finally reach the Planet of Eternal Life.
After the adventures of "The Rebels of Tuglan", Perry Rhodan and crew return to Vega to restart their final calculations to get to the Planet of Eternal Life - only to find that Vega's sun is very quickly turning into a supernova. Rhodan must hurry to get to his final destination in order to help save the citizens of Ferrol.
They finally arrive on the Planet of Eternal Life - only to find that it, too, holds many secrets that need to be solved before "The Immortal Unknown" grants immortality. Rhodan and his Mutant Corps travel thru a version of a Wild West town that could only come from the imagination of a truly alien being. Rhodan quickly solves the final riddles, and then he and a few hand picked others approach the final encounter with the being they come to call "PEL" (short for "Planet of Eternal Life").
When the Arkonides Krest and Thora approach the throne to receive what they believe is their reward, they find they are mistaken - it is Perry Rhodan and Terra to whom the final secret of Eternal Life will be given. Although that secret is not without cost - Rhodan discovers that the treatment must be given once every 62 years in order to maintain the vitality of the first time you first step into the cellular rejuvenator. Next, a whole new "band" of stories begins with "Venus In Danger".
I've never been this impressed by any series. I'm reminded of cliffhangers like "Buck Rodgers" or "Flash Gordon" when reading these marvelous books - a series that is still being published in Germany and is now well over 1,800 volumes. It's too bad American publishers stopped these after only about 120 books. I had to learn to speak, read, and write German in order to continue reading Perry Rhodan.
This book also contains another editorial, another science fiction movie section, and another fan letters page. Well worth reading the entire series.
