I am primarily writing this review as a warning for readers who perhaps are not comfortable handling the subject matter of this book and are not blindsided by its content. This is your content warning: This book contains extreme psychological abuse, physical abuse, harm of animals, a plot line involving a younger sister who has severe down's syndrome, and a general feeling of intense constant dread as you figure out in advance what is coming along in the upcoming chapters. That being said, I loved this book and highly recommend it if you can handle this type of content. 
 The premise is this: to their friends, Grace and Jack Angel appear to have the perfect marriage. Jack is the perfect gentleman, lovingly doting on his adoring wife who goes out of her way to make sure everything is perfect. Perfect Perfect Perfect. Except for the fact that since their marriage began, Jack has engaged in a ruthless and diabolical campaign of psychological torture of Grace, leaving no physical marks but forcing Grace to walk the thinest of lines while questioning her reality. Oh, and while also being the perfect husband, Jack is also a high profile domestic abuse lawyer, helping put away abusive husbands. 
 There's so more depth to Jack's plans and Grace's attempts to free herself within a certain time frame, but part of the enjoyment (if you can call it that) of the book was me realizing just a few pages before Grace did what Jack had planned, and feeling a physical sense of dread watching his plan be brought to light. Again, this was a difficult book to go through. I loved it, but also do not recommend it lightly. My husband at one point told me that he needed me to stop talking about the book to him because just hearing about what Jack was doing was upsetting him too much. 
 I will also say, after being burned multiple times this year on mystery/horror novels having a great set up and failing to deliver on the ending, I found the ending of this novel fairly satisfying. There were a few things I would have liked more closure on, a few scenes I'd have liked to have seen given what all I witnessed earlier in the book, but as a whole, the author delivered on the promises she had made and I wasn't left disappointed.
