Query: A must read for Stephen King fans!

This complete novel in itself is an imaginitive, brilliant piece of science fiction. Combine it with the fact that it ties together "Rose Madder" and "The Dark Tower" series and you have an even greater appreciation for just how deep into his imagination King can travel. This novel is full of characters who are so real, you'd swear they were living right in your own neighborhood. King has really written something different here. If you choose to read it, do so with an open mind and be prepared to be taken on a vast journey into yet another albiet unique story about good vs. evil. To truly get the most enjoyment out of this book, I would recommend first reading: "Rose Madder", "The Dark Tower" series, and "Eyes of the Dragon". After reading these pre-requisites and "Insomnia" I'm sure you'll agree that King is really on to something special
