I like reading books about war dogs, shipwrecks, and lady aviators.
I typically like books with dislikable characters; the flaws are so fascinating. In Gone Girl, the book this one is so frequently (and erroneously) compared to, pure sociopathy came to life in a way that furthered the storyline.
Here, the characters are horrendous simply for the sake of being horrendous. It was as if the author wanted to see just how far she could explode her unbelievable world.
It's also highly triggering if you've ever struggled with your weight or relationship to food. The main character is an obsessive binger, again, just for the sake of being one, narratively. There's frequent discussion of the Dukan diet, pounds lost, sizes dropped... none of it put me in a good headspace.
...I guess I don't actually have anything redeeming to throw at this one. :/
