For me, this book was quite similar to A Head Full of Ghosts, but more satisfying (especially when it came to the ending). It skirts a similar line of alluding to the supernatural without ever really confirming or denying the real cause of some events, which is something I find compellingly realistic in this type of fiction. While it took me a little while to really get rolling, once I did, I read the second half of the book pretty quickly and didn't want to put it down until I got to the end. This book is definitely horrifying, both in realistic ways and in nightmarish potentially supernatural ways, and I have to say I hope Paul Tremblay continues to write stories in this vein for a long time to come.
