I really enjoyed this read. It contains 4 "short" stories. I put short in quotes as the book itself is rather long, so 3 of the short stories really felt like reasonable-sized books all in of themselves. From what I understand one of these stories is a sort of sequel to another of King's works. I could not tell. It was fun and self-contained so I felt nothing lacking for not having read the first work. 

Two of these stories were a solid 5 star for me. I loved them, felt thoroughly creeped out and intrigued. The other two were a solid 4 star. Each story was thoroughly enjoyable and while I've really only read true short stories by King, these longer "short" stories have confirmed to me that I need to dig into some of his proper novels.
