We rate Prisoner B-3087 as IE (Intense, mostly emotional) because the content sits in the "Intense" range — intense conflict including peril, frightening scenes, or emotionally heavy themes. The strongest signals come from emotional weight, physical peril, social complexity — these are the dimensions parents should evaluate against their reader's tolerance.

Thematically, Prisoner B-3087 explores history, holocaust, survival, coming of age, and family — these threads give the book room to mean different things to different readers. Each of these themes is concrete enough to seed a real conversation, not just a moral lesson.
