This is a good book. I liked it! This one kind of goes with Desperation. They aren't really a series or anything, but they kind of go together. I don't know how to explain without spoiling the books. If you get both books & read them, you'll see what I mean.
Ok, I searched to see if I could find a way to explain it better. Wikipedia did a really good job, without spoiling the stories. This is copied & pasted from the beginning of the article:
The Regulators is a novel by Stephen King under the pseudonym Richard Bachman. It was published in 1996 at the same time as its "mirror" novel, Desperation. The two novels represent parallel universes relative to one another, and most of the characters present in one novel's world also exist in the other novel's reality, albeit in different circumstances. Additionally, the hardcover first editions of each novel, if set side by side, make a complete painting, and on the back of each cover is also a peek at the opposite's cover.
