Wow! A colossal novel by Stephen King; another colossal success for him. And by colossal I mean size; this book would make a good door stop if you could put it down that long. However, it is far too compelling to be set aside.
Jake Epping is a high school English teacher who loves his job. He teaches GED courses during the summer. One of the reasons he is divorced, according to his ex-wife, is that he is not in touch with his feelings. He gives his GED students the essay topic, "The Day That Changed My Life". And gets from Harry, the high school janitor, a description of the night his father murdered his family. Jake cried over this essay. Soon he was given the opportunity to go back in time through a portal in Al's Diner. He decides to save Harry's family. He also tries to stop the Kennedy assassination. But the past is obdurate and resists change. And no good deed goes unpunished.
Stephen King is well known for horror stories; this novel is found in the science fiction section of the library. (Thank goodness, I can't, and won't, read horror any longer. The nightmares are too close.) There is suspense in 11/22/63, but not much to disturb the sleep. It's well researched, well written, and moves very quickly in spite of being so large. A real tour de force. Highly enjoyable and recommended.
