Most people who enjoyed "Gone Girl" and "Girl on a Train" will probably enjoy this thriller, by the author of, "In a Dark, Dark Wood." I can't completely knock it because it was a page-turner than I plowed through in two days on a beach vacation. It started strong and reminded me of an Agatha Christie-style whodunnit with a fixed cast of characters to choose from.

My issues with it:
1. I hate unreliable protagonists. I just wanted to smack this woman and tell her to stop drinking.
2. The ending was a let down. After taking hundreds of pages to build the suspense, you can just wrap it in a chapter. That makes me think the author was under deadline pressure and decided to take a shortcut.
3. Loose threads. There were a few early elements that had a lot of potential to put a bow on this story, had been subtly woven through the story and resurfaced at the end. Instead, they were completely neglected, which not only robbed this book of a nice final ZING, but also left me with niggling questions about why the author even included them.

So. I'm going to say that most people who seek out thrillers for beach reads will enjoy this. I just wanted more from it.
