The Ghost Cache at Coyote Peak
Emily and Quinn are following a scavenger-hunt clue when they uncover a coded map tied to Coyote Peak's mining past. The map points to a ghost cache, a treasure rumor, and a sealed route through weather that can turn dangerous fast. But they are not the only ones on the trail. Someone is shadowing every clue, sabotaging Trail Quest, and will do whatever it takes to reach the cache first. With a storm rolling over the mountain, the girls must crack the code and decide who can be trusted before the trail closes behind them.
