Secret codes—lost landmarks—hidden clues—real locations

Before Jake’s grandfather died, he was on the trail of a centuries-old mystery. And he has entrusted that mystery to Jake, leaving behind a set of hidden codes, riddles, maps, and other clues that lead Jake and his friends on a scavenger hunt into the heart of Colorado’s wild and rugged Rocky Mountain National Park.

Through twists and turns, the mystery unfolds while Jake, Amber, and Wes learn about survival skills, natural history, integrity, character, and friendship.

Along the way, they discover they are not the only ones on this quest. An elusive shadow group is close on their heels.

This fast-paced adventure is designed to capture the imagination of even the most reluctant of young listeners. Parents looking for a delightful adventure will find it hard to pause. (Word of caution: Listeners frequently note that this is a “Please play just one more chapter” book).
