The RV Adventure Twins: The Lighthouse Code Mystery

By C L Donaldson

Summer break was supposed to mean salty air, sandy dunes, and family road-trip fun-not secret signals and a mystery that could put lives at risk.

When preteen twins Piper and Miles Morrow arrive in the Outer Banks with their teacher parents and their lovable dachshund, Moby, they expect lighthouse tours and beach sunsets. But strange things start happening fast: the lighthouse beam seems to blink in a pattern... a mysterious "321" tag appears where it shouldn't... and someone begins leaving warnings that feel meant for them.

Miles records every clue in his Case File notebook. Piper follows her instincts. And Moby's nose has a way of finding what others miss.

As the twins dig into real coastal history and local legends, they realize the "code" isn't just a game-it's a distraction. And if they can't crack it in time, the wrong signal could cause a real disaster.

Can Piper and Miles solve the lighthouse mystery before the next blink changes everything?
