I have really enjoyed reading this book the last few days. It had such an interesting plot that sometimes I struggled to put it down. This book is really well written and smart. It drags you in from the first page and leaves you wondering what the hell is happening and how it can possibly all end. Arnie and Sarah were great characters. Although sometimes I judged their decisions, I also understood that this was an intense situation and they were probably absolutely terrified. I was particularly scared for Sarah and this only heightend with the psychologist situation! What I enjoyed the most was not knowing what was real and what was not. So it became clear that Arnie was having intense nightmares and horrible hullcinations, but I started to wonder, is this actually an implant causing problems or is this a deeper issue? Can we trust the doctor? Is he up to no good or are we actually following an unreliable narrative here? This deffo gripped me to the book as I couldn't decide if this was legit happening the way Arnie thought it was, or it was all part of a mental breakdown - especially due to his desire to keep the little boy in his dreams, a possible version of himself, safe. The ending was impossible to put down as it was one big showdown with constant action. I was biting my nails wondering what could possibly be next when I felt like the story was already so close to finishing up. This is an interesting and gripping book. I recommend to anyone who loves a thriller. It would make an excellent book club discussion.

I was totally hooked from the very start and was unable to put it down, my need to find out what happened to Arnold was too great. An excellent read, thoroughly recommended.
