How to Read the Secret Explorers Books

Publication order is simplest, starting with The Lost Whales. The team and headquarters recur, but each mission focuses on different experts and can be understood on its own.

Families can also choose by interest—a dinosaur rescue, moon mission, rainforest, volcano, castle, cave, or ocean adventure. Mission notes, quizzes, and glossaries reinforce the real facts.
