The Everglades Echo - C L Donaldson

When the Morrow family pulls the Silver Star into Everglades City, Florida, Miles, Piper, and their dachshund Moby are ready for another adventure-but they are not expecting the water itself to seem alive.

A strange booming echo rolls through the mangroves. Moby digs up an old brass route tag in the mud. And before long, the twins are following a trail of clues through hidden channels, shifting tides, and long-buried local history.

With the help of a sharp-eyed local girl, a steady park ranger, and a boat captain who knows these waters by heart, Miles and Piper begin to uncover the truth: someone else is racing to find a lost dispatch satchel hidden years ago during a storm run-and they will do almost anything to reach it first.

To solve the mystery, the twins must piece together the meaning of the echo, the timing of the tide, and the secret route hidden beyond the obvious answer.

Packed with suspense, heart, real history, and unforgettable scenery, The Everglades Echo is a page-turning middle-grade adventure perfect for readers who love smart kids, loyal dogs, hidden clues, and mysteries set in real American places.

The RV Adventure Twins series blends action, family, travel, and true-location discovery into fast, wholesome adventures kids will want to read again and again.
