This is a great book. C. S. Lewis is a master of intertwining Biblical messages into his stories and this book is no exception. I don't want to ruin it for anyone so I'll try to not say anything. But I thought the going 1300 years into the future was a really cool concept. It gave Narnia a unique edge to it. All I have to say is if you haven't read the Narnia series, you really need to. C. S. Lewis is an amazing author.
