The Eve who did not fall : Out of the silent planet, Perelandra

Aslan's country : The chronicles of Narnia: The magician's nephew ; The lion, the witch, and the wardrobe ; Prince Caspian ; The voyage of the Dawn Treader ; The silver chair ; The horse and his boy ; The last battle

Malevolence in action : The screwtape letters

The everlasting incorrigibles : The great divorce

The boy who went around the world : The pilgrim's regress

Getting a face two ways : That hideous strength

Getting a face two other ways : Till we have faces.
