In ‘Prince Caspian’, the second book in C.S. Lewis’s Chronicles of Narnia series, the Pevensie siblings—Peter, Susan, Edmund, and Lucy—return to the magical land of Narnia. The children are summoned back to Narnia by Prince Caspian who needs their help to reclaim his rightful throne from his evil uncle, King Miraz.
The children get back to Narnia when they are magically transported through a mysterious portal while they are in the train station in England. They find themselves in a forest in Narnia, where they quickly realize much time has passed since their last visit, and Narnia is under the rule of Miraz, who has driven the true Narnians into hiding.
The story unfolds as they join forces with Caspian and the Old Narnians to battle Miraz, plunging them into a series of adventures that culminate in a fierce battle for the fate of Narnia.
