When a flicker of light from an old island lighthouse draws attention to long-forgotten Cold War secrets, Ben, Holly, and the Fix-It-All crew find themselves chasing more than echoes—they’re chasing a legacy buried just beneath the surface of Seashell Key.
As layers of history unfold, a hidden relay station, a mysterious watcher, and a trail of cryptic clues reveal a decades-old attempt to protect something too valuable to forget. But the more they uncover, the more they realize someone else is still watching… and they aren’t ready to let the past go.
The Lighthouse Echo is the thirteenth installment in the Seashell Key Mysteries, a feel-good cozy mystery series set in a quirky Gulf Coast town full of porch gossip, found family, and just the right amount of danger.
Once more the Seashell Key friends proved they could have an adventure field trip and still remain true to the island’s past without disturbing things someone might’ve wanted to keep hidden, or at least on the down low. They’re always super respectful of history even while having a good time.
