Daniel and the demure, and slightly shy Gabby are due to go on holiday to Kefalonia. Gabby, having received a bonus from work, treats herself to some clothes. Realizing she hadn’t bought much for Daniel, she sees an e-book in the window of a second-hand shop. With only one story loaded, she reads the synopsis and sees that it is a rom-com, knowing it's not Daniel’s style but still buys it for him. When he reads the synopsis, he finds the story to be a violent action thriller. He decides to save the book until they are on holiday, and in the run-up, the weather in Britain turns unseasonably cold. As he starts to read the story, he discovers it is a spy thriller but begins to notice strange similarities between the characters in the story and their own experiences. The more he reads, the more uncomfortable he becomes. He speaks to Gabby about it, but she dismisses it as a coincidence. He notices words changing as he reads them, and the e-book seems to be communicating with him. Gradually, the story starts to predict their future, a future full of danger. He feels compelled to continue reading and ignores Gabby, driving her into the arms of another man to fulfil her desires that Daniel wasn’t giving her. Too late, he finds out that he must never stop reading.
