CS Lewis wrote the Chronicles of Narnia in which The Lion, the Witch, and the Wardrobe is the second book. The book opens with the four children being evacuated from London during World War II. When they discover a secret doorway to Narnia through the back of a wardrobe in a strange old country house, they find themselves in a land of continuous winter. Soon they become embroiled in a war between the fantastical creatures of Narnia. With so much war and metaphorical darkness it is easy to see why Matilda feels there are no 'funny bits' in the books.
