What is the narrator point of view in the novel, Colin Fischer?

Colin Fisher is written in the third person, yet the narrator is not omniscient. Readers understand Colin's thought process and point of view, and see the world through his eyes: he reads the facial expressions of other so readers know what they are thinking, but only rarely do readers get a glimpse into the thoughts of someone else, like Mr. Fischer or Dr. Doran. But Melissa Greer's motives remain mysterious; readers never know for sure if she is simply a nice, generous girl or if she has romantic feelings for Colin. Because Colin himself cannot read such emotions yet, readers are doubly in the dark. Similarly, Colin cannot read Rudy Moore, so readers cannot get a grip on his true personality or motivations, except through his final interaction with Wayne, when Wayne accuses him of messing with the people around him out of malicious curiosity.
