This was my first read by this author so I wasn't sure what to expect especially after hearing mixed things. The plot focuses on a couple who move to a new house with state of art security, but is all really as it seems....The book had me gripped straight away and soon got into the story rather than dragging it out and the short chapters meant that you fly through. There were parts which I though were maybe a bit unbelievable but it also makes you think that this could be the way we live in years to come. It is a very up to date modern thriller as AI surrounds us now and it shows how heavily our lives revolve around technology without us maybe realising. I think the book would work very well adapted for TV or a film.
