Rachel Turner loves horses. One day while she's riding on a mountain trail with her friends, she hears the legend of the horse that used to live here before being killed in a terrible accident. Right then, it starts raining just like it did in the story, followed by jolts of lightning. When Rachel's horse panics, she finds herself thrown off, just like the girl who perished in the story. She sees a glimpse of the mystical, glistening ghost horse, and finds she can't take her mind off him. She's determined to find him and figure out the story behind him and his rider, who might be more connected to Rachel than she thought.
