On a class trip, you tour a real, working ship. But what if you got locked in—alone? In this book, readers use engineering knowledge they have and gain from the main text in order to solve a series of puzzles. Once solved, they can escape from the ship! Clues are found on every page, encouraging readers to read carefully and use their critical thinking skills to find and work out each one. Simple machines, engineering drawing, cogs, and more are part of the STEAM content of this book.
