I have two passages in a sci-fi novel I'm working on where the protaganist hears a voice. The mechanics aren't important, but the medium is unfamiliar to the hero, The long and short is he needs to have a conversation with this character which is difficult and frustrating for him. The way I have done it is with a series of two word sentences that reads a little like "Who's on first?" A couple of my readers hated it, finding it very frustrating to read and felt it was the worst part of the book. One other thought it was brilliant and understood exactly what I was trying to do. Any opinions on how to handle something like this? I've already pared it down as much as I could so as not to belabor the point.
