The Yellowstone Trail Trap

By C.L. Donaldson

When a dusty brass medallion turns up at Yellowstone's north entrance, twins Miles and Piper Morrow know their family road trip just became a case.

With their clever dachshund Moby leading the way, the RV Adventure Twins are pulled into a hidden trail of old postcards, missing route pieces, mysterious historic markers, and a long-buried Yellowstone story that someone does not want told the right way. As clues lead them from Mammoth Hot Springs to Norris Geyser Basin, Old Faithful, Grand Prismatic, Lamar Valley, West Thumb, and beyond, Miles and Piper must figure out which clues are real, which ones are planted, and who is trying to steer them toward the wrong ending.

Along the way, they meet a guarded girl with a family connection to the mystery, a polished history personality who always seems to be one step too close, and a truth buried deep in Yellowstone's past. To solve the case, the twins must stop thinking like treasure hunters and start thinking like the person who needed the truth to survive longer than the story.

Packed with real Yellowstone history, geothermal wonders, wildlife, family teamwork, and a smart, page-turning mystery, The Yellowstone Trail Trap is a thrilling middle-grade adventure perfect for readers who love national parks, hidden clues, and brave kids who never stop asking questions.
