On the Moon is one of four books in our Treasure Hunt Puzzles series. You’re on a tour of a space research facility and board an experimental spaceship that accidentally launches. You’re on your own flying to the Moon! This is a special kind of book. It contains a story with lots of puzzles that lead you on an adventure. You must land on the Moon and return to Earth – all by working out codes and coordinates, solving maths and spatial puzzles, and much more. Plus, remember your answers to unlock one final puzzle for a safe touchdown!
