Susan Pevensie is a fictional major character of C. S. Lewis's The Chronicles of Narnia series. Susan is the elder sister and the second eldest Pevensie child. She appears in three of the seven books—as a child in The Lion, the Witch and the Wardrobe and Prince Caspian, and as an adult in The Horse and His Boy. She is also mentioned in The Voyage of the Dawn Treader and The Last Battle. During her reign at the Narnian capital of Cair Paravel, she is known as Queen Susan the Gentle or Queen Susan of the Horn. She was the only Pevensie that survived the train wreck (because she was not on the train or at the station) on Earth which sent the others to Narnia after The Last Battle.
