What is the author's style in Xenocide by Orson Scott Card?

The novel is written from a third person, omniscient and retrospective point of view using almost all of the characters as reflector characters at one point or another. This point of view is necessary considering the scope of events Card depicts within the novel, events that span two planets and a good deal of the space in between. Within a single chapter the narration shifts from Path to Lusitania or to several different locations on Lusitania.
