I could not put this book down! Loved it--top notch Stephen King. His characters are so real. Full of suspense. Not a horror novel, but some horrific things. But, also characters that your admire. Mr. Mercedes is a mass murderer, who thinks he's gotten away with it. And is getting restless, he'd like to out-do himself, but he also wants to rub it in the face of the cop that didn't catch it the first time.
