There are a few similiar patterns with Gillian Flynn's Gone Girl which I have found in this facepalm of a book. First, the story revolves between a husband and a wife, but in this case, the heroine is divorced from her husband but involved, just the same. Second, the alternating POVs. In Gone Girl, the two narrators have distinct voices; you can distinguish whose POV it is. Here, I sometimes forget who is talking, and there are three of them, for Flynn's sake! They all sound alike. Yes, their situations vary from each others', but the way they talk is pretty much the same. Third, the "baby news". [Yawns.] 
 I wanted to like this, but somehow it fell short of twists. The protagonist is the stupidest character I have ever met in my literary life. The ending is amazingly predictable. So much for these Gone Girl wannabes.
