A 3.5, but I can’t bring myself to give it that fourth star that goodreads requires since there’s no half star rating system. I have a lot of feelings to process about this book, but the biggest one is that the main character and narrator was the biggest mansplaining, self absorbed, egotistical asshole I’ve ever metaphorically met and I just….I’ve never disliked a main character more. He was not likable and obviously I don’t think he was supposed to be. That’s the thing about unreliable narrators. Majority of the time, you don’t like them, but it’s okay because it adds to the story. My dislike for Theo didn’t really cause me to have an issue with this book. The flow of events and the timeline intertwine and show you just how connected Theo and Alicia are. In my opinion, the story was moving extremely slow until we get to see Alicia’s diary. When that comes into play (not just in her narrating, but in her actually giving it to Theo), that is when the events of the story begin to pick up and everything begins to spiral. Secrets are uncovered, betrayals discovered and we’re show just how unstable our main character is. I guessed part of the twist pretty early on through Alicia’s narrations, but still, it was a pretty intriguing book. Best thriller of the year though? Not in my opinion.
