I'm trying to remember the name/series of this book that I read (at least) a few years ago.
It had a sci-fi space travel theme, but was mostly set on this planet that had "zones" that kept people separated by making them ill/or causing pain.
From what I remember they traveled using some sort of FTL system that caused the ship to split into multiple copies of itself, and one of the captains told the computer to destroy all the other copies of the ship. The ship(s) also traveled through time for some reason, and ended up at the planet (I think like 1,000+) years before they were supposed to.
I believe they were trying to prepare the planet for habitation before the main ship arrived carrying refuges or a main landing party.
Hope this is enough to trigger someone's recollection, as I have been looking for this book for a while now because I'm sure it was only the first in a series...
