The phantom horse returns . . .
Callie Fern can't wait to take her first trail ride. It's just what she needs to take her mind off Star, who has rejoined her owner in the ghost world. But on the trail, the horses go wild and run off, leaving Callie, her friend Amy, and her sister, Melissa, stranded in the mountains. Huge storm clouds are racing in, and with Melissa's ankle sprained from her fall, the girls can't get to shelter. Even worse, Callie spies a stranger following them.
Suddenly she feels the familiar tingle up her spine that can only mean Star is near! Callie needs Star's help, but can she share the ghost horse's secret? Before the night is over, Callie - and Star - may learn to open their hearts in ways they never expected. . .
