Caverns, Clues, and Cowboys

At Blue Lagoon Cowboy Camp in the heart of Texas, twin sisters Samantha and Lizzie Brown are gearing up to teach a group of kids how to rope, ride, and embrace the cowboy way. But as the final preparations are being made, a chance discovery threatens the fabric of their idyllic small town.

While scouting the campgrounds, the twins stumble upon a hidden cave…one that's not on any map. Deep inside the cavernous maze, they find more than just adventure—they discover a frightened Dalmatian puppy standing guard over bags of cash, the spoils of a notorious armored car heist.

But when they return with the sheriff, the money—and any trace of the crime—has vanished. With law enforcement convinced the report is nothing more than an elaborate prank, the twins are more determined than ever to uncover the truth. Samantha taps into her investigative skills as a local reporter, while Lizzie, a savvy assistant to a private investigator, digs into the secret lives of their fellow camp counselors. Each clue leads them closer to unmasking a hidden criminal, but the deeper they go, the more perilous their search becomes.

With the clock ticking and the camp set to open in less than twenty-four hours, can Samantha and Lizzie track down the hidden robber? Or will the secrets buried in the Blue Lagoon caves prove to be more than they can handle?
