King of the Wind (1949) by Marguerite Henry, illustrated by Wesley Dennis, is a Newbery Medal-winning children's novel that tells the story of Sham, an Arabian horse, and Agba, the mute stableboy who devotes his life to him. Born in Morocco under conflicting omens, Sham faces hardship and mistreatment as he and Agba journey from royal stables to foreign lands, including France and England. Despite being overlooked and cast aside, Sham proves his worth, ultimately becoming the legendary Godolphin Arabian, the foundation sire of modern thoroughbred racehorses. The novel is a moving tale of loyalty, perseverance, and the unbreakable bond between a boy and his horse.
