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.
