Meg would do almost anything to get to Mustang Mountain Ranch even put up with snobby friend, Alison. They're going to spend the whole summer with Alison's cousin Becky on a ranch high up in the Rocky Mountains.Meg wants a horse so badly. Maybe she'll find a horse on the ranch that will be her special friend. But at the last minute, their trip is delayed and they head into the mountains too late.
A sudden storm, an icy road - an adventure begins that will take Meg, Alison and Becky far off the beaten track to a place where cougars, wild mustangs and grizzly bears roam free.
To reach Mustang Mountain, they will need every scrap of courage they possess.
