It'd usually only take me a day to read a book of this size, but I started this one a couple of weeks ago and only just finished today.

Why? Well, I could say I've been too busy, but to be honest if I'm really into a book I make time to read no matter what.
There's nothing wrong with the writing, or the characters and I enjoyed the idea of the story - but I wonder if the fact that King says right from the start, "this isn't really a story in that it doesn't have an end" in other words "unsolved mystery", I wonder if that disengaged my interest on some level?

Regardless of this, I still spent a very pleasant hour finishing the book (ok, so I read it in the pub with a nice cold pint and a side order of home fries) but it didn't grab me...what did you think?
