I just started Fire Upon the Deep yesterday. It's confusing, and I don't know why so many people seem to like it. I'm not really having fun because I don't know what's going on and I can't keep anything or anyone straight. The plot threads have no obvious connection to each other and the author seems to be having way too much fun tantalizing me with incomplete worldbuilding details. I'm up to page 109: someone tell me what makes the other 500 pages worth reading, please.
