I initially gave this a 2 or 3, because King had put himself into the plot and made himself the center of the magic [for lack of a more appropriate term].But this is a continuation to [b:Wolves of the Calla 4978 Wolves of the Calla (The Dark Tower, #5) Stephen King https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1419360231l/4978.SY75.jpg 2754911] which is my favorite in the series. This one has more plot movement and more references to the overlapping stories, including another of my King favorites [b:Rose Madder 10619 Rose Madder Stephen King https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1660826989l/10619.SY75.jpg 833191], and even more overlapping Earths. And so I've changed my rating to 4.

While this is certainly not a terrible book when compared to other works, it is nonetheless one if the weakest of the Dark Tower novels for me personally. The narrative seems disjointed and the strongest aspect of the series, Mid World and its many strange coincidences, are missing for the vast majority if the story. Despite that it does at least rush us headlong into the conclusive book of the series and serves to give Roland and his companions some impetus on the final stretch to the field of roses and the Dark Tower.
