Since moving west over a decade ago, Tom Groneberg has worked with horses as a trail guide, as a ranch hand, and as the manager of his own ranch in Montana, but he has never owned a really good horse. Until, on an autumn night, in a warm barn under a blanket of snow, Blue is born. Soon, he will belong to Tom Groneberg. "If I had a good horse," writes Tom, "I could give it my life. I could ride it for years. We could grow old together." So begins this unique American love story about a man and his horse.

In straightforward, poetic prose, Tom Groneberg chronicles the early successes and failures of trying to train Blue, earning the animal's trust, and saddling him for the first time. The experience is challenging, but ultimately rewarding for Tom. Through his relationship with the animal, he develops a deeper understanding of the land and his community, and of himself - as a man, and as a husband and father. In a world in which horses are fast becoming nothing more than warm-blooded lawn ornaments, Tom still believes these animals are important in human lives.

At its heart, One Good Horse is about the power of hope, the simple story of a horse and the way people connect with nature and with each other across the generations.
