This was an OK, kind of dark and kind of fun thriller. It’s not a spoiler to say the narrator is an antihero; she’s a psychologist who is also a serial killer. I found it kind of annoying that Ruby seems to be very insightful, except when it comes to her crimes. She is constantly beating it into the reader that it was OK for her to commit her crimes because these were bad people doing bad things and someone needed to stop them. Never does she consider the impact it may have on those around the victims, their families, friends, loved ones. It makes her seem truly cold and not half as smart as she thinks she is. I was hoping she’d get caught.
