The duo makes a house swap in Paris with a couple they meet online but the supposedly luxurious apartment is run-down and they are unable to contact the couple.
They return home after a series of increasingly unsettling events, with neither able to shake the feeling that theres now something sinister about their own home.
Macmillan will publish the book in July.
