In the Jungle is one of four books in our Treasure Hunt Puzzles series. You’re on a trek along the famous Inca trail, when you find yourself falling down into a deep valley… you’re trapped! This is a special kind of book. It contains a story with lots of puzzles that lead you on an adventure. You’ll have to navigate mazes, crack codes and encrypted messages, and work out letter and number problems. And remember your answers to solve one final challenge to return to the Inca trail.
