Caught! Land Border- Paperback

A line of cars a mile long. A gas tank that holds no gas. A jacket that's very slightly... moving.

Roll down your window and enter the secret world of the land crossing — the busiest doorway of all, where the cargo rides on wheels. Watch officers read a car in two seconds, X-ray a whole truck without stopping it, uncover a tunnel dug beneath a warehouse, find reptiles sewn into a smuggler's jacket, and guard a nation's cattle from a tiny, dangerous tick.

Caught! Land Border is real-cases, real-science nonfiction that reads like a detective story, showing curious kids the ingenious tools — and teamwork — that keep a continent's goods honest and moving. Each chapter ends with a true "This Really Happened" case, and the book closes with a glossary, a quiz, and the real careers behind the hunt.

Book 3 of the Caught! series. Also available: Seaport (Book 1) and Airport (Book 2).
