The unknown immortal who guards that most devoutly despired secret, the secret of eternal life, seemingly has prepared an endless series of tests, "impossible" challenges that anyone must meet and beat who would win the secret of secrets.

Perry Rhodan, leader of the New Power, has already gone ahead too far in his pursuit to ever think of going back - even if he wanted to. Following an adventure that has strained the nervous systems of all involved to the utmost limit, he finally has in his possession a further clue from the unknown one.

And this message is the curtain-raiser to the (so far) most incredible adventure of the Peacelord of the Universe, his - Quest Through Space and Time.
