Eleven-year-old Serilda Shaw is a true child of Northern Missouri. Her life in 1866 is bound by an intense love of the frontier country and a great affection for animals. When she intervenes in the shooting of a mare, she is determined to nurse her and prove that she is a fine thoroughbred. Sherilda's resolve, strengthened by diligence and courage, is rewarded when the pedigree is finally established. A counter theme of friendship between Sherilda and a waif-like child round off this story which abounds in attractive contemporary detail and historical color.
