Interference (ON HOLD)

I'm writing this for National Novel Writing Month 2011. That means editing is at the bottom of my list of duties. I'll get to that in December. So if things don't flow exactly write, or there are some mistakes, I apologize in advance.

D is a Traveler. Working from a central commune, she travels to specified planets at pre-determined moments in time to interfere with the fate of one person's life. To ensure that they do not fulfill their destiny. D loves her position, but recently, the job hasn't been as satisfying as it used to be.
A Veil, as they call themselves, never interferes with the same life more than once. But now D has been asked to return to a life she's already saved once. To step in and do it again. The more she digs, the more she wonders if she's doing the right thing. Have her actions been the cause of more pain and agony? Is it time to step up and question or just do the job?
