Who is the narrator, can she or he read minds, and, more importantly, can we trust her or him?
First Person (Central); Third Person (Omniscient)
There are two narrative techniques employed throughout The Angel Experiment. For the most part, it's in the first person with Max as the central narrator—meaning that we get the whole run-down from Max's perspective. For us as readers, this helps us really care about Max. Her experience is central to our reading experience, plus we get to know her best by hanging out inside her head.
But whenever the flock is apart (like when Iggy and the Gasman are left behind while the other flock members rush off to save Angel), the book sometimes switches to a third person omniscient narrator. These sections allow us to see what the other flock members are doing and thinking when they're away from Max, so it's not a complete mystery. Doing this makes sure that the story, while structured around Max primarily, maintains its allegiance to the flock—just like Max does.
