The Motor Boys Over the Rockies; Or, A Mystery of the Air

A tight‑knit gang of teenage adventurers spends their lazy summer afternoons debating where to steer their trusty airship next. With personalities that clash as loudly as their engines—Bob’s bold ideas, Ned’s cool logic, Jerry’s steady calm, and the ever‑cheerful Chunky—they decide a Western jaunt across the Rockies will be the perfect escape from the heat.

Their plans take a sudden turn when the airship is mysteriously taken, leaving the boys to chase clues through rugged mountain passes and dusty mining camps. Along the way they encounter secretive locals, puzzling telegrams, and a missing professor whose inventions could change the course of their journey. The early part of the story blends high‑flying ingenuity with the rugged charm of the frontier, promising a thrilling race against time as the Motor Boys race to uncover the truth behind the stolen craft.
