What is the author's style in Titanic Survivors Found in Bermuda Triangle by Robert Olen Butler?

Readers may find this story difficult to follow because the first-person point of view restricts the narrative and takes them from one time frame to another without explaining what is going on. The story takes place within Margaret's head and is placed so deeply within her consciousness that it does not identify places where one thought leads to another. Because the background is not established for specific scenes, readers have to interpret the clues around them in order to figure out what is going on.
