What's the Story?
Back in the 1950s, a British botanist and his daughter Rosalind, who didn't let her blindness keep her from studying along with him, traveled the world exploring THE GREEN KINGDOM of plants. Meanwhile, she kept up a lively correspondence with her sister, Minna, a famed needleworker, who lived and worked in Brooklyn, New York. Each letter includes a series of riddles and clues from science and ancient tales about plants. Fast-forward to the present, when 12-year-old Caspia, a small-town girl from Maine, spends the summer in what was once Minna's apartment. Caspia finds the letters, and soon has half the neighborhood, plus her pals back home, working to solve the riddles.
Is It Any Good?
It's all about the plants in this enticing summer tale of old letters, riddles, and new possibilities, as a tween discovers Brooklyn, makes new friends, learns a lot, and puts down roots. Longtime fans of author Cornelia Funke, known for her work in the realms of magic and fantasy, may be surprised at The Green Kingdom's change of pace: She joins forces with ethnobotanist Tammi Hartung to introduce a wealth of information about plants, as seen in myth, story, science, art, food, and more, but it's an engaging and informative read that opens up many paths for future exploration. The info-packed narrative can sometimes overwhelm the sweet, relatable story of a family finding itself during a summer away, but this fun, friendship-centered, community-building tale paired with Melissa Castrillón's plentiful, detailed black-and-white illustrations of plants is not to be missed.
