I have not read the Chronicles of Narnia aloud for almost thirty years, but have the current good fortune to be reading The Lion, The Witch and The Wardrobe to my granddaughters, and double fortune to be reading the sacrifice, death and resurrection chapters during Holy Week. I notice different things when I read aloud, especially in the descriptions. LWW is about Edmund's betrayal, but once one has read the entire series, Susan's eventual betrayal of Narnia is in the background upon rereading. I choked up today reading to the girls the section where Susan and Lucy walk at night with Aslan to the Stone Table, touching his mane, stroking and comforting him. Susan's affection for him is so powerful in that scene. How could you? I thought. How could you turn away from what you once knew?
Well, how could any of us, but we do it all the time.
If anyone wants to go down the rabbit hole of JK Rowling huffily accusing Lewis of sexism in his description of Susan no longer being a friend of Narnia, I wrote a defense Sexism in Narnia in 2007. I still agree with what I wrote then, though I might write it up differently. Bsking commented knowledgeably at the time - more important, she agreed with me - and my son Ben, who used to read this site and is deeply knowledgeable about children's literature, commented as well. He commented at enough length that it became a post at his own site, Books for Boys, Books for Girls, and the comments there inspired me to write a further post on Female Characters in Heroic Fantasy.
