Oh, I loved this right off the mark.  It starts off strong, introducing serial killer Edmund Reese who inexplicable disappears from the electric chair as he's being executed.  Where did he go?  Was it real or was it made up to make the boogey man even scarier? What does this have to do with the family we are introduced to next?  There are so many threads tying everything together, when it all comes together it's so satisfying.

You KNOW the big bad is going to come, you just don't know who it going to happen to or when.  The style of Wendig's writing, jumping abruptly from character to character, jumping from past to present, the short chapters, it all keeps you unsettled and adds to the atmosphere.  I read this book in small bursts, I had to put it down fairly often to get some distance from it. I definitely thought about it while I wasn't reading it.  This book reminds me of the old school creepy horror novels I used to read, in the best way!  If you want something to keep you up at night, either because you are reading it or thinking about it, this is it.
