I've read most of Okorafor's other novels, so it was interesting to finally read her debut. This book really reflects her love of nature, and I recognized some elements of this book that had been remixed in her later work. My library categorized this as young adult, but I would say it's very middle grade, especially towards the end. I really enjoyed the plant-based technology in the Kingdom of Ooni and the variety of creatures that can be found in the Forbidden Greeny Jungle. I wished Okorafor had given a pseudo-science explanation for the plant computers and plant satellites because I was so enthralled with the idea of living tech. Zahrah is a very timid character, and I enjoyed reading about her growth, and her friendship with Dari.
