What is the narrator point of view in the novel, Lake Success?

The novel’s narration is written in the past tense and the third person. The only two point-of-view characters in the novel are Barry and Seema, meaning they are the only two characters whose thoughts and emotions are conveyed directly to the reader. However, the novel never gives the perspective of both Barry and Seema at the same time. The novel alternates the point of view by chapter, so in each given chapter, there is only one point-of-view character.
