as much as i would like her too, i'm not sure that susan does get back on the right track. In most of the Narnia books ahve some sort of an allegory to them,a nd I think Lewis may have intended susan to represent those who get of the right track and don't ever find their way back. I'd like to say that I think she does, but I don't think she does.
That's odd from Gresham, because it was in a book called CS Lewis' Letters to Children that I read, in Lewis' own words, the assurance that Susan still had time to return to belief in Narnia, and that he felt she would! If I come across the book here, I will put in the quote, but I am sure I read that.
Why did the Pevensie parents die as well? I don't think it further the plot very much at all, and it was a bit of coincidence. Is there some meaning behind it that I'm missing?

Even though C.S. Lewis never said what happened to Susan for sure, I personally always thought that this sudden isolation would force her to re-evaluate her life and priorities, and lead her to seek Aslan as He is in our world. We know that she and Peter probably had a similar conversation with Aslan at the end of Prince Caspian as Lucy and Edmund had in Voyage of the Dawn Treader, because Peter says, at the end of Prince Caspian, that "It's all rather different from what I thought. You'll understand when it comes to your last time." That means Susan knows that, if she's willing to look, she can find Aslan in England, too, and I really think she would.
Oh, and Narnia was never destroyed. It was the shadow of Narnia that was destroyed. All the characters (except Susan) find themselves in the real Narnia at the end of the LB. Why would you want to undo the destruction of a shadow? No one would want to go back to that shadow after they had experienced the “more real� Narnia.
