What is the author's style in the novel, A World Between?

Unlike some other Spinrad works, A World Between is not venturesome in style. Its story is told directly, with cuts to scenes involving important characters or events. The one added feature is the frequent use of commercials from the media campaigns. These are described fully, including technical details like "The camera moves in for a closeup" or "Male voiceover." The commercials are given in present tense.
