The last one put me in a weird state of mind because I had spent a few years of my life on the series. I found the first three book super engrossing and even the fourth kinda.
No joke, The Drawing of the Three and The Waste Lands might be the two most engrossing books I’ve ever read. I am going through these WAY faster than I normally go through novels. I’m not even sure I would say this is my favorite Stephen King thing I’ve read yet, but it is probably the most compelling.
