Read the passage from The Lion, the Witch, and the Wardrobe. "What’s that noise?” said Lucy suddenly. It was a far larger house than she had ever been in before and the thought of all those long passages and rows of doors leading into empty rooms was beginning to make her feel a little creepy. "It’s only a bird, silly,” said Edmund. "It’s an owl,” said Peter. "This is going to be a wonderful place for birds. I shall go to bed now. I say, let’s go and explore tomorrow. You might find anything in a place like this. Did you see those mountains as we came along? And the woods? There might be eagles. There might be stags. There’ll be hawks.” –The Lion, the Witch, and the Wardrobe, C. S. Lewis
