After seventy-three days in a renovated Bluebird bus, Addy discovers a sticky note on a restroom mirror in her dead grandmother’s unmistakable shaky cursive.
The yellow square holds the first clue in a scientific scavenger hunt down Route 66.
At first, Addy keeps the note to herself. But once she shares it with her sisters, their RVschool journey takes a wild detour into roadside mysteries, clue-filled challenges, and one unforgettable trip down America’s Mother Road.
Perfect for fans of From the Mixed-Up Files of Mrs. Basil E. Frankweiler and The Vanderbeekers, this lighthearted mystery celebrates adventure, sisterhood, and curiosity on the open road.
