Good quote ....
"I want to tell you something Mark, something you do not yet know, but we K-PAXians have been around long enough to have discovered.
The Universe will expand, and then it will collapse back on itself, and then it will expand again. It will repeat this process forever.
What you don't know is that when the Universe expands again everything will be as it is now. Whatever mistakes you make this time around you will live through on your next pass. Every mistake you make you will live through again and again, forever.
So my advice to you is to get it right this time around because this time is all you have."
I also noticed that there is a sequel to the original novel, and the last part of the trilogy will be published in July .... I would love to read these books.
