Jake Epping, an English teacher from Lisbon Falls, discovers an extraordinary secret: the storeroom in a local diner is a portal to 1958. Leaving behind the world of iPods and mobile phones for a world of Elvis, big American cars and Lindy Hopping, Jake sets on an insane – and insanely possible – mission: to try and prevent the assassination  of John F. Kennedy.But all is not ‘swell’ in the world of 1958 – it’s also the world of  troubled loner Lee Harvey Oswald, and a beautiful high school librarian named Sadie Dunhill, who will become the love of Jake’s life…and does the past want to be changed? Will the past allow change?
