Roland's journey has finally come to an end after countless pages. The ending is supposed to be as well-known as "Luke, I am your father," but somehow I wasn't aware of it. I hope no one tells you!
This is a magnificent conclusion to an extraordinary fantasy series. It's evident that this isn't just any ordinary book for Stephen King, who publishes two books a year but took over 30 years to finish this story. And when the author invests so much effort into a work, it shows.
The resolution isn't equally satisfying for all the characters involved, and there is a rather obvious deus ex machina that they even warn you about. But in general, I can't give it less than five stars...
