Very very interesting your review! I have been reading and listening to different reviews and this one resonated so much to me. Because, I think the same about the message of the book and how pew could be a metaphor. I listened to an interview with the author (you can have it here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-b8vydtk5dGE.html) and she explains what she wanted to say creating this character this way. To me is more as how a person grows and changes perspective on life and how unfamiliar can look a place that was very familiar to you.
