BLUF: Great story with a poor ending.
The premise of this book is pretty simple. Wife goes missing. Husband didn't do it. Police think he did. It's an irresistible storyline.
Which is why you will keep reading even after you realize that the husband is a dope, the wife is likeable but socially ridiculous, and that the story continues despite having nothing interesting to share...
...but then there is a twist. It's wonderful. Even though you don't care about the players, you cannot put this book down. Sorry for the cliche, but it's like watching a car wreck - you just cannot look away, for better or worse.
Which is fortunate because, while it gets better, the ending is not satisfying.
The reason I marked this as a recommended title is because I couldn't stop talking to people about this book after the twist. I rarely share like this.
