The Green Kingdom

A gentle children’s and young teenager story about plants, clues, and finding your place. Caspia spends eleven weeks in Brooklyn, where she discovers a stack of old letters filled with botanical riddles. As she solves each one, she builds a small garden and slowly grows new “roots” in the city. The independence she’s given as a twelve‑year‑old feels unrealistic at times, and her parents remain thinly sketched, but the plant lore, cosy mystery elements, and themes of belonging make it an engaging read for younger readers. Informative, warm, and easy to follow — perfect for ages 9–12 who enjoy nature‑based stories.
