This book is formatted in what is now a fairly rare style, but one that I used to see a lot in paperbacks when I was a kid. Two stories, starting at opposite ends of the book. So one cover is upside down to the other one, depending on which story you are reading. What I don't like about that (didn't care about when I was a kid) is that I track my reading by total number of pages, and this one starts over at both ends of the book.
So I read the Stephen King story first, which is 58 pages, and then the other story, which is 88 pages, so I had to do math to track my reading on the day that I stopped about 2/3 of the way through the second story. I don't like it when reading makes me do math.
All that aside, this was a fun little book and an easy two-day read for me. For some, it would be a quick one-sitting read, I'm sure.
The Chizmar story, I'm sorry to say, was actually better than the Stephen King story. No, I'm not sorry to say that. I'm not sure why I said that. The King/O'Nan (they have teamed up before, most notably in Faithful, the book they started writing together at the beginning of the 2004 baseball season, having no idea that their beloved Boston Red Sox would break the 84-year-old "Curse of the Bambino" that season) story, is actually about baseball. Sort of. Dean Evers is a baseball fan who used to live in New England and was a Red Sox fan. But he moved to Florida and adopted the Rays (right there makes the book a horror story . . .) as his home team. So he watches them every night, but he's alone, because his wife passed away, not too long ago. The horror aspect comes into play when he starts seeing people behind home plate . . . people he shouldn't be seeing. Dead people, in fact, and they are telling him things. It's a quick read, and pretty well-written, but far from my favorite King work. The ending is somewhat predictable, as well, I thought.
Chizmar's story (I thought I had not read him, before, but he co-wrote Gwendy's Button Box with King) involves a couple finding out that their next door neighbor isn't who they believed him to be. There's nothing supernaturally horrific about this story, but as the tale unfolds, it gets more and more horrible, with a not totally predictable ending. As I said, I liked it better than the King/O'Nan story.
I do wish that the editors had made both stories in the same font. That was a little off-putting.
I would recommend this book to anyone looking for a quick, easy read in the genre in which Stephen King generally writes.
