What This Book Is About

The Secret Explorers are a team of brilliant kids from around the world, each with a special area of expertise. When the Exploration Station sends out a signal, they know it's time for a new mission. This time, rainforest expert Ollie and marine biologist Connor are transported deep into the Amazon rainforest, where illegal loggers are threatening to destroy a critical section of jungle—and the animals that call it home.

Armed with real science knowledge and quick thinking, the two explorers must find a way to stop the destruction before it's too late. Along the way, readers learn fascinating facts about rainforest ecosystems, endangered species, and why these forests matter for the entire planet. Published by DK, the book blends fiction with non-fiction seamlessly, featuring illustrated fact boxes, maps, and a quiz at the end. It's part of a popular series with over fifteen titles, each tackling a different scientific adventure—from deep-sea diving to dinosaur fossils.

Available at Popular bookstores, Kinokuniya, and the Singapore National Library.

Why We Recommend This Book

The Secret Explorers series is brilliant for building non-fiction reading skills through the backdoor of adventure fiction. Grade 3 students at international schools need to read informational texts across science and social studies, but many children find pure non-fiction dry. This series solves that problem by wrapping real scientific content in an exciting story with characters kids care about.

The rainforest theme connects directly to UWC's emphasis on environmental sustainability and global citizenship. Students learn about deforestation, biodiversity, and conservation—topics that appear frequently in international school curricula. At 128 pages with generous illustrations, the book is perfectly sized for young readers building stamina and confidence.
