Light is intensely challenging. It follows three characters in different places and times: Kearney is a contemporary scientist/serial-murderer; Seria Mau is a distant-future pilot of a K-ship; and Ed Chianese is a former pilot, also in the distant future. Each plot line contains several unexplained components that only make sense through repeated exposure to their use in context, and the connections between the characters are very slowly revealed. There are several secondary characters who turn out to be merely tangential.

The juxtaposition of the three plot threads was well executed, and the prose is often quite artful, but I remain frustrated that the main characters' motivations were only sketched. I believe that the novel would be much more clear on re-reading, but I hate re-reading, so that will remain a hunch.
