Esther couldn't believe her ears. She and her sisters were going to spend the summer with grandma and Hank on their Montana ranch. And that meant she'd see wild horses!

It was an exciting summer. They were big pigs and frisky calves to ride. Best of all, wild horses room everywhere.

Esther love to watch them reread Buck, galloping through the fields with their tales and means flying in the wind.

Maybe that was because Esther was a bit wild, too. She invented all sorts of trouble to get her sisters and cousins into. She didn't mean them any harm. But somehow things turned out much worse than she had planned.

Then she met Queenie, while stubborn horse that Hank just couldn't train. And Queenie taught Esther lesson that summer that she would never forget.
