I just finished reading the entire Dark Tower Series for the first time (minus The Wind Through the Keyhole) 3 nights ago. I can't stop thinking about the ending. I loved it! But I'm trying to make sense of it. There are a lot of posts I have seen online that talk about the ending. There are a hundred different theories from readers about what the ending means, which I believe is a great reason the ending is done so well. Questions that I pose here are: What is the significance of the Horn of Eld? Did Roland go back in time every time he starts the loop or does he start further in the future? Does he draw the same three every time? And what are the implications of the answers to these questions? Start with the question about whether or not Roland goes back in time or not. I believed that he did. I believed that when he came back to the desert chasing Walter, he was back at whatever time it was in the beginning of the first book. Some people don't believe that is true. But I have a question then. If he advanced in the future (or started with the present time he entered the tower), wouldn't Stephen King's life in this world already be over? Would Roland then draw a different three people? On the other hand, I can see why him going back to the past is also questionable. If he is only to draw the same three again, in their same when and where, then what's the point of Eddie, Susanna, and Jake living together at the end? If he starts all over again, then there is no point in including that part of it because they'll just be re-drawn and have no future together in the "other" New York. Remember that in The Wastelands, they come to River Crossing and the town folk talk about how there was a gunslinger who had come through about a hundred years ago. Was that Roland? I also want to know what your opinions are on the significance of the Horn of Eld. Does this mean it is Roland's last time he has to do this? Does he learn something new every time he does this loop until he finally gets everything right? Does he simply need the right pieces when he arrives at the tower? I'd love to hear your opinions on the horn, whether you think he goes back in time every time, whether he draws the same three, and whatever other thoughts you have about the ending! I eagerly await your responses.
