Everyone needs loyalty, love and at times healing. Lucky is the soul who finds all three In the Heart of a Mustang.
A boy is told that his father was a brave and virtuous man, a soldier who traded his life to save the lives of countless others. He was the man that Hunter needed to emulate. The only problem is the story is a lie, all of it. The truth, which Hunter discovers as he begins his sophomore year of high school, is that his father has actually spent the boy's entire life in jail, paying his debt to society, but not mending his ways.
A wild mustang mare is rounded up by the BLM. The spring rains had been sparse, the forage on the plains even more so. The mare and her herd are rescued from certain starvation and placed for adoption. In a sandy corral at Promise Ranch, a home for troubled teenage boys, the boy and the mare meet. A weathered old cowboy brings them together - a mentor for one, a trainer for the other.
The bond that forms between boy and horse becomes one that saves the lives of both.
