Bakken Books ad: Adventure Starts Here.

Join Isaiah, Sadie, and Ethan as they board the Giddy Galleon with their grandfather and uncover a mystery that starts with one hidden note: “Five lakes. Five clues.” What follows is a five-book treasure hunt packed with shipwreck secrets, strange legends, stormy waters, hidden ciphers, rival treasure hunters, and one final discovery bigger than gold. For kids who loved The Campground Kids, this is the next big adventure. Same curious kids. Same page-turning mystery. A whole new world of danger, history, and treasure.
