The Newbery Medal-winning author of Walk Two Moons and Absolutely Normal Chaos takes listeners on an adventure brimming with mystery, buried treasure, and the healing power of cookies. Nicknamed the "trouble twins," 13- year-old brother and sister Dallas and Florida have long since given up hope of ever finding a family. Then they meet Tiller and Sairy, an eccentric older couple looking for some help with one last adventure while they're still spry enough to paddle a canoe and climb a mountain.
