Book grabs you and never lets you go. Time travel, changing history (alternate reality), love story, history lesson-it all works together. Story stayed with me when I had to put book down to do mundane everyday things. Couldn't wait to get back to it.
Not a huge Stephen King fan, actually haven't read any of his stuff since the mid-80s, but what a storyteller! Loved that he didn't shy away from the good or bad of the early 60s instead met them head on. I'd be surprised if a movie wasn't made.
