On November 22, 1963, three shots rang out in Dallas, killing President Kennedy, and changing the world. What if it could be changed? In this brilliant novel, Stephen King masterfully captures the social, political, and cultural conditions of his generation with unprecedented thoroughness, taking readers on an astonishing journey into the past and exploring the possibility of changing it. The story begins with Jake Epping, an English teacher in Lisbon Falls, Maine, who earns extra money teaching GCSE classes. He assigns his students essays about an event that changed their lives. One of the essays shocks him: a horrific story that took place on the night more than fifty years earlier when Harry Denning's father came to the house and killed his mother, sister, and brother with a sledgehammer. Reading the essay represents a watershed moment for Jake, and his life changes, just as Harry's life and American history changed in 1963. Everything changed in the blink of an eye. And after Not long after Jake reads the article, he meets his friend Al, who owns a local restaurant, and Al confides in him that the pantry at his restaurant is a portal to the past, to a specific day in 1958. Al chooses Jake to take on what has become his obsession: preventing the assassination of Kennedy.
