What is the author's style in Wondrous Strange by Lesley Livingston?

The novel is written from the third-person point of view, from the perspective of author and narrator of the novel. The novel swings back and forth between the present and the past. The present represents the time after Kelley and Sonny came to the mortal world. The past represents the time leading up to the closing of the gates that led to Sonny and Kelley living in the mortal world.
