I would call it quarantine reading but we would have done it anyways. Having finished The Hobbit, an intro to Narnia seemed the next, logical step.
But I have come to deeply appreciate Lewis, overall, in recent years, and I was glad to introduce my daughter to him. We have put Prince Caspian on hold at the library, but what I really want to read to her is The Horse and His Boy, which, as a child, I might have read even more times than Wardrobe. It is, so far as I can tell, not highly respected, but I found it to be a lovely and beautiful self contained adventure.
