One of the all-time great pleasures is having a good story read to you. Miss Cook, my fifth-grade teacher, would read us a chapter from The Lion, the Witch and the Wardrobe every day. Of course, reading a good story to yourself is fun, too, and to this day, every time I open up the battered old boxed set we've had since I was a child, I swear that I can smell Narnia in the pages.
Out of all the books ever written for children, the The Chronicles of Narnia have to rank among the best. There is adventure, and wild animals, and magic, and child protagonists, and happy endings. But there is also a depth to the stories which makes them bear up well upon repeated re-reading. But, of course, knowing Lewis, you would expect the stories to be infused with Christian values, and so they are, but even when you expect them, you can't always spot the allusions. In fact, the best way to read Lewis is to alternate between his fiction and his non-fiction, because the fiction illustrates the points he is making in his essays, and his essays reveal the points he is making in his fiction.
Some people try to introduce new people to Narnia by telling them that it's essentially a re-telling of the Bible. Certainly, the account of the creation of Narnia in The Magician's Nephew has parallels with Genesis, and the account of the end of Narnia in The Last Battle has parallels with Revelation, but one of Lewis' convictions is that God is too big to write himself across all of space and time once, and therefore has no need to repeat Himself. Thus, he tries to make Narnia unique, and I'd say he succeeded. Nevertheless, he does have important truths to say about God, perhaps best summed up when Rilian, the last king of Narnia, says of Aslan, "He's not a tame lion."
If you haven't read The Chronicles of Narnia yet, you owe it to yourself. Then, you should read them to your children, or grandchildren. Just don't tell them it's good for them. Greg Slade
