It's a rather ripe old age, but it's still sad to see him go, because, if you haven't had the pleasure of experiencing it yet, The Phantom Tollbooth is one of the most imaginative children's books ever written, and I highly recommend that you read it at least once in your life.
Thanks, Mr. Juster, for such a truly wild ride.
