A whole volume of the Perelandra books was devoted to preventing original sin by another planet's Adam and Eve, I think it was on Venus.
A nice touch in the Perelandra books was the angels manifesting themselves with respect to an absolute frame of reference.
I liked “A Wrinkle in Time,” but I didn’t remember it dealing with original sin.
It only sorta dealt with that subject. Each planet had reached a different “level”.
