Grey, S L: The Apartment (Paperback)

Mark and Steph are struggling to move on with their lives after armed robbers broke into their home and brutalized them. Shaken, they decide to get away and leave their troubles behind. A house swap in Paris with a couple they meet online, the Petits, seems to provide the perfect escape. Once home, neither of them can shake the feeling that there's now something sinister about their own house ... In the vein of Stephen King.
