Shelving note: hand this to readers who crave sense-of-wonder anchored by blue-collar sci-fi textures and ethical stakes. Strong appeal for fans of urban futures, exploratory SF, and stories where tech sings instead of shouts.
Content/age guidance for classrooms and clubs: non-graphic peril, corporate/syndicate intimidation, brief references to resource scarcity and infrastructure failure, sustained tension during descent sequences. Great discussion prompts on stewardship vs exploitation, who controls power, and how science can be both song and tool. I'd recommend for mature teens and adults, especially groups interested in science-and-society conversations.
