This book was outstanding. One of my favorite Stephen King’s for sure. It’s the story of Jake Epping, high school teacher who gets a call from his friend Al. Al wants to show him something in his restaurant. It just happens to be a time portal in his pantry. When you go through it, you arrive in September 1958. Al wants Jake to go through and save the life of President Kennedy in 1963. But the past is obdurate; it doesn’t want to be changed. Excellent book.
