The Mystery at Dolphin Cove
Avery, Ella, and Evan love dolphins! They especially love to visit their grandparents at Palmetto Bluff and go out on the Mimi in hopes of seeing dolphins up close. But when dolphins begin to disappear along the coast, the kids research the facts, figure out clues, and race against time to save their dolphin friends, Marco and Polo. In the course of the story, they learn how dolphins communicate, dolphin facts, and a little about 3D printing!
