The Magician's Nephew is my favorite of C.S. Lewis' The Chronicles of Narnia. (At least it was when I read them all in college. That may have changed.) I have always imagined sharing some of my favorite books with the boys and having them love them just as much as I do. Of course like many of my relational fantasies, this one didn't quite work out.
For the past few years the boys have been listening on and off to the cd's of the Chronicles. They have enjoyed these, but haven't "loved" them. I have also read The Lion, The Witch and The Wardrobe to the prior to this. So when I suggested that we read the TMN, Caleb said, "That's boewing (boring). I already know what's going to happen next." They have humored me though. Ben seems to really enjoy it and Caleb at least lays quietly. I love these books and look forward to continuing with the others at a later point. If you're thinking about buying the CD's, I might recommend not. There are some books that should be shared with your kids. The CD's seem to not have enough "weight", if that makes sense.
