When I started this one I wasn't expecting much. It was an impulse buy at a resale shop and it was a King novel I had never heard of at the time. It went on the "to-read" shelf in my room and I forgot about it. 
 Once I finally did get around to opening it I couldn't put it down. What a surprise that was. I'm not sure I would say that it's one of King's best, but it's certainly unique and I found it to be one of his scariest books. Who would have thought that a novel with really only one character in it could be so nerve-wracking, but I found the Space Cowboy parts to be genuinely tense and scary novels almost never succeed in actually scaring me. 
 The plot of the book sounds horrible and I guess that's probably why it's so obscure. If I wasn't on a huge King kick right now I probably would have passed it up in the store. 
 The ending is weak and I feel like a broken record saying this, because it seems like I say this in every review I ever do for a Stephen King book, but he just seems to always lose all forward momentum in the last ten percent of his books. I won't spoil it, but I felt that it was a pretty cheap way to deal with the cowboy. If there's one thing King has in abundance it's imagination and I feel like he could have used it a little better and thought up something a little more interesting than what he did.
