I don't normally read psychological thrillers because they trigger issues for me but this is our book club book this month so I read it. It's a good story. I was sucked into from the first moment (of course, I did have all the lights on.) I guessed what was happening to her within the first chapter and I was right. I knew her husband was up to no good and I was right. I did not guess the murderer and was only half right on the reason for the murder. I was guessing up to the end on how it would all fall into place. Luck was on Cass' side and she deserved it. I'll read this author again.
