2.5 stars. 
 I received an electronic version of this title from Netgalley, so it's only fair that I offer my honest review. 
 On the negative side, the writing is mediocre, the surprise-twist-ending felt lame, and I was glad I was done, instead of left wanting more. 
 On the plus side, I never wanted to stop reading it, and my tolerance is pretty low. The premise seemed so much more promising than the delivery, really. In order to rent a high-tech, unusual, low-rent house, tenants must sign a lengthy contract. Then, essentially, bad things happen. 
 Fans of Gone Girl will finish it, and many will probably really like it, based on the current Goodreads rating score. Yet it never felt as compelling as that title. I hear that a movie adaptation will happen, directed by Ron Howard. I would watch the movie, and maybe this is even the sort of thing that works better in that format, and feels a bit less cheesy. Still, I was entertained.
