At the name of Aslan each one of the children felt something jump in its inside. Edmund felt a sensation of mysterious horror. Peter felt suddenly brave and adventurous. Susan felt as if some delicious smell or some delightful strain of music had just floated by her. And Lucy got the feeling you have when you wake up in the morning and realize that it is the beginning of the holidays or the beginning of summer.
-C.S. Lewis, The Lion, the Witch and the Wardrobe
