The Galactic Riddle

EDITORIAL REVIEW:Thora and others mentioned that they are on a quest to find the Planet of Eternal Life as early as "Enterprise Stardust," but it is with this book, The Galactic Riddle, that Perry's quest for this secret begins. "The Galactic Riddle" begins to be solved when Rhodan and his allies pull the rest of the secrets from an unusual storage facility in the dungeons of Ferrol, the eighth planet of the Vega system.  This vault is protected, not by locks or bars, but by time itself, truly, this is... THE GALACTIC RIDDLE!
