Adventure in Grand Canyon National Park

National Park Mystery, Book #3

Before Jake's grandfather died, he was on the trail of a centuries-old mystery. 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 while camping in the most rugged wilderness of the national parks.

Follow the clues to real locations on a quest to solve an ancient mystery.

The scavenger hunt takes Jake and his friends, where few people venture to go, into the depths of the Grand Canyon.

Jake, Amber, and Wes encounter new dangers and find their friendship tested as they follow the clues Jake's grandfather hid away in the old scrapbook. The stakes are higher, and the history goes deeper as the three kids put their heads together to solve a puzzle that is perhaps hundreds of years in the making.
