The storyline of The Horse and His Boy unfolds during Narnia's Golden Age, a period when Peter the High King, along with Queens Lucy and Susan and King Edmund, govern the land. This book offers a rare glimpse into the lives of the Pevensies as mature rulers and provides the most detailed depiction of Calormen within "The Chronicles of Narnia." In this tale, two talking horses, a slave boy, and a girl from Calormene nobility escape northward through Calormen, aiming to reach the Desert and beyond. Their goal is to find a place free from slavery, where talking horses can live without fear, and where a girl cannot be forced into marriage against her will.
