About River of Gold

Unlock Hidden Treasure and Defend a Sacred Land in The River of Gold—A Thrilling Middle-Grade Mystery Adventure!

Spending a few weeks in rural New Mexico, Mogi Franklin and his sister, Jennifer, expect a quiet summer of rafting and relaxation. But when they stumble upon an old legend about gold stolen in a long-forgotten stagecoach robbery, their curiosity turns into a high-stakes quest.  

The stakes grow even higher when plans for a massive power plant threaten to destroy the serene river valley…and the historic monastery that has called it home for generations. With time running out, the siblings must use every ounce of wit and courage to uncover the treasure, protect the land, and stop a powerful corporation in its tracks. But with corporate sabotage, hidden clues, and even a ghost standing in their way, the journey won’t be easy.  

The River of Gold is the ninth thrilling installment in the Mogi Franklin Mystery series, packed with adventure, environmental themes, and the enduring power of family, logic, and bravery.
