“Macadoo’s response to his struggles will resonate with readers.” —School Library Journal When Macadoo is just a colt, he challenges his father—a huge Belgian stallion—in order to protect his dam. From that moment on, Mac knows that his purpose in life is to help others. From surviving a kill auction to learning how to be a vaulting horse to giving therapeutic riding lessons, Mac is always patient and never loses hope in his mission to serve others—and he finds the courage to “walk on” through even the most difficult circumstances.
