What is the narrator point of view in the novel, The Last Romantics?

At the beginning of the novel, in particular with the first chapter titled “Year 2079,” and then Chapter 1, it appears that the novel will be told using a conventional first-person narrator, the main character Fiona Skinner. However, as the novel progresses, it will switch back-and-forth without notice between this first-person perspective, a third-person omniscient narrator, and the very unconventional first-person omniscient narrator.
