Many authors write their novels based on their past experiences, and C.S. Lewis is no different. Lewis based the stories of Narnia on his childhood in Northern Ireland. What’s there to do in Northern Ireland, you ask? Well, for C.S. Lewis, not much. In fact, that’s why Lucy is apparently able to conjure up imaginary worlds in empty rooms, because that’s exactly what he and his brother did in their spare time. And when Lewis’s mother died, he tried to convey his emotions through writing about Prince Caspian’s loss of his son.
