I'm also jumping the gun because I just finished Run Afoul, which I talked about last week, today. So technically, I'm between books at the moment. However, I am going to start The Lion, the Witch, and the Wardrobe (part of the Narnia Reading Challenge) in a couple of hours. So I'm going to use the first line from that today.
There once were four children whose names were Peter, Susan, Edmund, and Lucy.
Okay, so it's not especially catchy or brilliant or anything. But this book holds such fonds memories for me that I can't help but smile when I read those words.
