Kids shouldn't build zip-lines. Everyone knows that. Zip-lines are dangerous. Caves too. They should stay away from caves. And secret passages? Don't get me started on those! Above all, kids shouldn't go picking up strange slingshots that tumble off garbage trucks. If they do, they might accidentally get entangled in a mystery, and I think we can all agree that kids have no business getting tied up in mysteries. Come to think of it, kids shouldn't even read this book. It'll just give them ideas...
Inside the The Slingshot's Secret are clues leading to a real life hidden treasure. Read the story. Find the clues. Hunt for the treasure.
