What is the author's style in Still Missing by Chevy Stevens?

The point of view of this novel is the first person. The format of this novel is unusual. Each chapter is written as though it is a one sided recording of a therapy session between the main character, Annie O'Sullivan, and her psychiatrist, Nadine. For this reason, much of the narration is written in a sort of dialogue between Annie and Nadine, though the reader is only allowed to hear Annie's side of things. There is other dialogue in the novel as well, conversations that Annie relates to Nadine, but again it is all done in the frame of Annie's voice.
