The horse and his boy

The novel is set in the period covered by the last chapter of The Lion, the Witch, and the Wardrobe (which was the first of the Narnia books to be published), during the reign of the four Pevensie children as Kings and Queens of Narnia. Though three of the Pevensies appear as minor characters in The Horse and His Boy, the main characters are two children and two talking horses who escape from Calormen and travel north into Narnia. On their journey, they pass through Calormen's capital city; while there, they learn of Calormen's plan to invade Archenland. When they reach Archenland, they warn the king of the impending invasion.
