Peter Lundy has two joys in life: the rugged western plains where he has grown up and San Domingo, a Medicine Hat Stallion. The Indians believe such a horse is sacred -- that neither bullet nor arrow can harm its rider. As they explore the prairie together, a bond forms between Peter and San Domingo that can never be broken. But Peter's father, Jethro Lundy, knows only one love: bargaining. He trades San Domingo for a thoroughbred. How can Peter ever forgive his father? His only choice is to leave home forever!
Marguerite Henry (1902–1997) was the beloved author of such classic horse stories as King of the Wind, Misty of Chincoteague, and Stormy, Misty’s Foal, and her work has won several Newbery Awards and Honors.
