At first, I kindof worried this would end up being a dry, overly-science not-enough-fiction story, but then I noticed it was by Robert Silverberg and kept listening. The plot seemed transparent at first, the femme-fatale hired by the rival businessman to take down the protagonist, blah blah etc etc. Then, it turned out that wasn't the plot at all, and I was way off. Near the end, when I realized what was actually happening, this story became one of my favourites. I think the ending is perhaps the most important part: two people with powers they cannot use as long as they are together. What ramifications does this have, considering they were born with them, and therefore destined to use them? Could it be that now they are together, they no longer need them, for their mutual goals have been accomplished?
Yet another good Silverberg story, I hope to hear more of his stuff on Escape Pod.
