The Campground Kids: Lost City Adventures

Book Series Description:

Ancient cities. Secret codes. Hidden treasure. One Lost City.

When their Uncle Elliott is mysteriously missing, Isaiah, Sadie, and Ethan discover that he left behind a coded trail connected to an ancient mystery.

With the help of an old artifact called the Navigem, the kids follow clues through real archaeological sites, ancient ruins, temples, jungles, and hidden passageways. Each stop brings new puzzles to solve, new questions to answer, and new reasons to wonder just how far the mystery goes.

But the deeper they follow the trail, the more they begin to suspect they may not be the only ones searching.

Packed with secret codes, ancient civilizations, real-world history, friendship, humor, and nonstop adventure, The Campground Kids: Lost City Adventures is a six-book journey for readers ages 8–12 who love mysteries, treasure hunts, and discovering what might be waiting just beyond the next clue.
