What is the author's style in Sapphique by Catherine Fisher?

The novel is written in the third-person point of view, from the perspective of the author and narrator. The novel swings back and forth between the present and the past. The present represents the time when Finn and Sapphique have left Incarceron. The past represents the time in history when Finn and Sapphique were still prisoners of Incarceron.

The point of view of this novel is intimate, allowing a reader to connect closely with several of the characters. The book written in this manner allows the reader to get inside the heads, thoughts and inner struggles of the characters. The reader cares what happens to the characters even though most of them struggle between good and evil. The point of view also allows the author to inject her own opinions into the narration and to expand on the events taking place around the other characters and the occurrences taking place.
