Science Geek Christy and her Eco-Logbook

Petra Crofton brings real scientific credentials — she works with the IUCN and A Rocha — and that shows in the environmental content, which covers carbon footprints, plastics, and food waste with more accuracy than most middle-grade eco fiction. The faith integration is organic rather than preachy, and the diary-logbook format gives Christy a distinct voice. The ideal audience is fairly narrow (Christian families with ecology-curious 8-to-12-year-olds), but within that lane it delivers well.
