The book is told through interspersed police investigations and primarily with the first person as Victoria relates all the events around Z and their relationship to Andrew. At the beginning, I found this a little awkward, but it quickly grew on me and I really enjoyed the style- it swept me up in the story, almost like I was a part of it. I really liked Vic, she seems like your typical shy, anxious teenager. Her POV was amazing. The romance between her and Z and her and Andrew felt very real/normal teenage angst but exacerbated by her anxiety.
There is a huge twist at the end- I had guessed at maybe parts of it, but not at the whole thing. Looking back, you can definitely find hints of it all, which makes it pretty chilling. It was masterfully done and took me completely by surprise. I am still in awe of this work- so dark and so thought-provoking. It's an incredible read; I am sure I will be thinking about it for a long time to come.
Please note that I received an ARC from the publisher through netgalley in exchange for my honest review.
