Book Beginnings for June 18th

It's Friday, which means it is time for this week's Book Beginnings on Friday.  This week, I've been rereading C.S. Lewis' The Magician's Nephew, the first (or sixth) of The Chronicles of Narnia.  Frankly, as much as I love these books, they don't have good first sentences.  And this one is no different.

This is a story about something that happened a long time ago when your grandfather was a child.
