I guess 3.5 is more on the level. I'm just not overly impressed with Ruth Ware's writing. I don't think this one needed to be in first person to show the main character's (who, frankly, was not very likable) personality. One thing that irked me was the phrases used to describe sudden events. I don't like when there's a preface of saying "and then it happened". It feels sophomoric and clumsy. Overall, the story was alright, and it was a quick read. It's a page turner which is a plus. The ending felt slightly rushed and unnecessarily baiting, but I did find it more entertaining than In a Dark, Dark Wood.
